Data displayed in Discoverer is different to source table...???
Hi,
I have written a few transform scripts that create a 'final' table - to be used by Discoverer. The table has been added into the EUL and I have created a simple worksheet based on the table.
I am getting some pretty strange results.
The table added to the EUL is called T_DLM_REC_REPORT.
When I run the following script directly against the table
SELECT SUM(REFERRALS)
FROM T_DLM_REC_REPORT_1
WHERE APP_DATE BETWEEN '01-NOV-2009' AND '30-NOV-2009'
I get a value 46820 returned.
When I create a simple worksheet with three fields (two of which are page items) I get a different result.
I have added the Referrals column into the worksheet - this defaults to show the SUM
I have also added APP_DATE: YEAR and APP_DATE: MONTH as page items.
Filtering by YEAR = 2009 and MONTH = NOV the worksheet returns 46749.
This is the SQL generated by the worksheet:
SELECT ( DECODE(O148011.APP_DATE,NULL,TO_DATE(NULL,'MMDDYYYY'),TO_DATE(TO_CHAR(TRUNC(O148011.APP_DATE,'MM'),'MM')||'1900','MMYYYY')) ), ( DECODE(O148011.APP_DATE,NULL,TO_DATE(NULL,'MMDDYYYY'),TO_DATE(TO_CHAR(TRUNC(O148011.APP_DATE,'YYYY'),'YYYY')||'01','YYYYMM')) ), SUM(O148011.REFERRALS)
FROM UGP.T_DLM_REC_REPORT_1 O148011
GROUP BY ( DECODE(O148011.APP_DATE,NULL,TO_DATE(NULL,'MMDDYYYY'),TO_DATE(TO_CHAR(TRUNC(O148011.APP_DATE,'MM'),'MM')||'1900','MMYYYY')) ), ( DECODE(O148011.APP_DATE,NULL,TO_DATE(NULL,'MMDDYYYY'),TO_DATE(TO_CHAR(TRUNC(O148011.APP_DATE,'YYYY'),'YYYY')||'01','YYYYMM')) )
Pretty long winded if you ask me.
Can anyone help explain the results I am getting.
Many thanks
Mark
Hi Mark
If you are getting the same answer from Discoverer as you get from the database with no filters applied this is good news. This means that you are at least pointing to the right table.
Here's the way I would go about tracking down what is going on.
Rather than filter by month or by the days of November I would extend the search to include some days prior to the beginning of November and some days into the beginning of the December. I would also include the date itself along with the sum of the referrals.
Next, I would manually look at November and add up the referrals. You will soon see where the error is and then you can adjust your condition accordingly.
Best wishes
Michael

Data type could be same base on source table for blank column
We have an employee table as mentioned structure.
EMPNO NUMBER(4),
ENAME VARCHAR2(10),
JOB VARCHAR2(9),
MGR NUMBER(4),
HIREDATE DATE,
SAL NUMBER(7,2),
COMM NUMBER(7,2),
DEPTNO NUMBER(2)
I want to create a view base on the same/exact structure data type-length. So is there any way we can define Data type while creating view.
Actually, I need to create a view base on above structure but only want to get deptno and sum of salary column from emp table and rest of column will remain blank.
ThanksSomething like this???
CREATE OR REPLACE VIEW v_tmp AS
SELECT NULL empno,
NULL ename,
NULL job,
NULL mgr,
NULL hiredate,
sal sal,
dept_no
FROM employees
GROUP BY dept_no;

Data Services Designer - Error when pulling large source tables
Hi all,
I have been trying yo load data from an SAP table - BSIS into MS SQL server database using BO Data Services Designer XI 3.2. It is a simple data flow with one souce table (BSIS).
When we execute the job, it says what is mentioned below:
*"Process to execute Dataflow is started"*
*"Cache statistics determined that DataFlow uses <0> caches with a total use of <0> bytes. This is less than the virtual memory <1609564160> bytes available for caches. Statistics is switching the cache type to IN MEMORY."*
*"Dataflow using IN MEMORY cache."
It stays there for a while and says "Dataflow terminated due to error"
In the error window, it says DF received a bad system message.
Does not specify the error... It asks to contact the customer support with error logs, ATL files and DDL scripts.
Can anyone help me out???
Thank you and regards,

please do not post the short dump in this forum.
I blieve the system will read from table dt_iobj_dest.
The problem is that 0FISCPER, 0FISCYEAR and 0FISCVARNT are not registered.
You can register the infoobject 0FISCYEAR and 0FISCVARNT
retroactively:
1) se24, CL_UG_BW_FIELD_MAPPING
2) F8 -> test environment
3) GET_INSTANCE, do not use IT_FIELD_RESTRICT

5) REGISTER_INFO_OBJECT
6) specify I_RFCDEST
I_INFOOBJECT

Multiple source tables for Measures dimension.
Hi,
We have two different SQL source tables for the Measure dimension in our project. Both the tables have the same structure but the Measures they contain are different. Based on certain condition Essbase will have to pick up Measures from one of the two tables. So basically the source table changes based on the condition. Is it possible to design rule files to achieve this? Please help me with this.
Thanks,
Krishnaas I am sure many will say essbase and load rules are not really an ETL tools.^^^ :)
Glenn is going to counter with a "I know how to do this in three steps using create column as text, join, and a oft-overlooked but awesome command that everyone but Tom Tortolani (I think I have the spelling on that right -- he was the Arbor employee that wrote Load Rules) forgot.
I 100% agree with John -- why not do it in SQL?

Date datatype in source and destinattion. But format is different in source
Hi
I have a proc that loads data from source table to destination table.
In the source table, I see the date is stored as yyyy/mm/dd. When i try to load from this source to destination, I get the following error:
SQLCODE -1861 SQLERRM ORA 01861 Literal string does not match the format string.Is there a way that I load from source to destination irrespective of the way date format used in source?
I cant do :
insert into destinationtable(datecol)
(select date1 from sourcetable)I get the above mentioned error.
Any help???Hi,
So date1 is a VARCHAR2 column, that's supposed to represent a date in 'yyyy/mm/dd' format, but sometimes contains text that is not in that format: is that the problem?
Here's a package function I've used for similar problems:
-- ** t o _ d t **
-- to_dt attempts to convert in_txt to a DATE using in_fmt_1_txt.
-- If that fails, it tries again, using in_fmt_2_txt.
-- If that fails, it tries again, using in_fmt_3_txt, and so on.
-- As soon as one conversion works, the function returns the DATE,
-- and the remaining formats are not tried.
-- If all the formats given fail, then NULL is returned.
FUNCTION to_dt
( in_txt VARCHAR2 -- string to be converted
, in_fmt_1_txt VARCHAR2 DEFAULT 'DD-Mon-YYYY' -- 1st format to try
, in_fmt_2_txt VARCHAR2 DEFAULT NULL -- 2nd format to try
, in_fmt_3_txt VARCHAR2 DEFAULT NULL -- 3rd format to try
, in_fmt_4_txt VARCHAR2 DEFAULT NULL -- 4th format to try
, in_fmt_5_txt VARCHAR2 DEFAULT NULL -- 5th format to try
RETURN DATE
DETERMINISTIC
IS
fmt_cnt PLS_INTEGER := 5; -- Number of in_fmt_ arguments
fmt_num PLS_INTEGER := 1; -- Number of argument being tried
return_dt DATE := NULL; -- To be returned
BEGIN
WHILE return_dt IS NULL
AND fmt_num <= fmt_cnt
LOOP
BEGIN -- Block to trap conversion errors
return_dt := TO_DATE ( in_txt
, CASE fmt_num
WHEN 1 THEN in_fmt_1_txt
WHEN 2 THEN in_fmt_2_txt
WHEN 3 THEN in_fmt_3_txt
WHEN 4 THEN in_fmt_4_txt
WHEN 5 THEN in_fmt_5_txt
END
EXCEPTION
WHEN OTHERS
THEN
NULL;
END; -- Block to trap conversion errors
fmt_num := fmt_num + 1;
END LOOP;
RETURN return_dt;
END to_dt
;The best solution, though, is to clean up the source table.
Identify the rows where date1 is not in 'yyyy/mm/dd' format.
If you can figure out what the correct data should be, UPDATE to that value.
If you can't figure out what the correct data should be, UPDATE to NULL. -
Hi Everyone,
Hopefully someone might have an explanation for the difference in counts.
Problem:
Excel 2013 on Windows 7
A Single excel spreadsheet with 2 data sources:
One created using "From Other Sources on the DATA tab which connects to SQL Server"
Second data source the same data as item 1, but in a differnet worksheet tab inside the workbook
[Sheet1] - Other SQL data Source
[Sheet2] - Exact Same data as Sheet1 but in a table
[PowerView] - 2 tables
Table one uses Sheet1 as its table data source
Table two uses Sheet2 as its table data source
When you Count(Not Blank) using the same criteria and fields for each table, the numbers dont match.
The one that has the incorrect count is when I use the Table data from [Sheet1] - which is the Other SQL Data Source
Testing:
I also created a standard pivot table using Excel and the counts then are both correct for both datasources. So it must be something in PowerView????

Multiple Language : Data Display Problem
Hi ,
I have one problem regarding NLS_LANG, please advice.
I have a table on source machine which stores the data in different language (German, Danish, Russian Cyrillic) but these data shows as "???????" on command prompt as well as on Toad when access it from client machine.
I know that displaying any kind of data depends on local NLS_LANG but what NLS_LANG I have to set so that it can display different language together. I am able to display data separately for German, Danish and Russian Cyrillic when I change NLS_LANG and location in client accordingly but unable to display all language together.
Default setting for NLS_LANG on client machine is AMERICAN_AMERICA.WE8MSWIN1252.
Please advise common NLS_LANG for all three language (German, Danish, Russian Cyrillic).
Thanking YouPl continue the discussion in your original thread for continuity purposes.
Multiple data display problem -
My Macbook Pro has been having slowness problems, and I just noticed some folders have unusual date displays: 2014 M04 17:50.
I have never seen the M, which must mean month before yesterday. Anybody have some light to shine on this?
I have run MacScan for tracking cookies and spyware- found 2 Safari tracking cookies, but nothing else. Also ran Adwaremedic- nothing found.Mac users often ask whether they should install "anti-virus" (AV) software. The usual answer is "no." That answer is right, but it may give the wrong impression that there is no threat from what are loosely called "viruses." There is a threat, and you need to educate yourself about it.
1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions.
It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to take control of it remotely. That threat is in a different category, and there's no easy way to defend against it. AV software is not intended to, and does not, defend against such attacks.
The comment is long because the issue is complex. The key points are in sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't been checked for security by Apple unless it comes from the App Store, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
☞ It can easily be disabled or overridden by the user.
☞ A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
Apple has taken far too long to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. Those lapses don't involve App Store products, however.
For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is a problem of human behavior, not machine behavior, and no technological fix alone is going to solve it. Trusting software to protect you will only make you more vulnerable.
The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and Internet criminals. If you're better informed than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
Software from an untrustworthy source
☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software. A genuine alert that Flash is outdated and blocked is shown on this support page. Follow the instructions on the support page in that case. Otherwise, assume that the alert is fake and someone is trying to scam you into installing malware. If you see such alerts on more than one website, ask for instructions.
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Rogue websites such as Softonic, Soft32, and CNET Download distribute free applications that have been packaged in a superfluous "installer."
☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
Software that is plainly illegal or does something illegal
☞ High-priced commercial software such as Photoshop is "cracked" or "free."
☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission. All "YouTube downloaders" are in this category, though not all are necessarily malicious.
Conditional or unsolicited offers from strangers
☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
☞ You win a prize in a contest you never entered.
☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
☞ A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
☞ Anything online that you would expect to pay for is "free."
Unexpected events
☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
☞ You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a padlock icon in the address bar when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial AV or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
Why shouldn't you use commercial AV products?
☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
☞ Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
☞ By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
☞ Most importantly, a false sense of security is dangerous.
8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It can be as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices. -
Data display grid font selection
Does anyone know how to change the font that's used on the "Data" tab when displaying the content of rows in a table?
I'm trying to view chinese characters which are stored in UTF-8 unicode in the database. I have all the necessary fonts loaded on my machine and the correct NLS_LANG settings.
I can see western characters, arabic, russian, greek OK in the data-grid, but not chinese or other far-eastern languages. Instead I see little squares instead of the symbols.
I've checked for font setting in Tools -> Preferences but the only setting I can find is under the "Code Editor" section. This is set correctly (to Arial Unicode MS) and if I copy the "little squares" from the data grid and paste them into a code-edit tab I see the characters correctly displayed.
So it seems that the "Font" setting for the code-edit tabs isn't used by the data-display tabs.
Is there a way of making both code-editor window and data-display tab use the same font?i would create a standard report.
i presume the air pressure and humidity are from one field? if not create a formula to display that.
create groups
1- a/p humidity field or formula
2- time
3- ref-measure- error
not sure if they are the same field or different.
you can then place your data in the groups (formulas calcs etc)
then underlay the groups so they appear on the same line
then draw boxes around them.
hope this helps -
How can I share data between two forms on different lists
Using a custom content type, I created two lists that I want to share the same data - one is a calendar. Our employees complete a form from the "Out of Office Request" list that has workflow functionality that sends an email to that person's
manager. If the manager approves the request, the item automatically populates the "Out of Office Calendar." The problem is that the only information from the request list that populates the calendar is the Title field and date/time fields.
I need the manager name in order to create a view for each manager.
How can I connect the other information in the request list to the calendar list. It seems to me that if the title and date fields carry over the information, there should be a way to connect the other information. I'm using Designer.
I've tried to connect the two lists' webparts with the wizard, but when I get to the page that maps the two lists, there are no column names and the "Next >" button is grayed out. This seems like the logical place to connect the two lists,
but it isn't working.Hi,
According to your post, my understanding is that you wanted share data between two forms on different lists.
To show external information on the calendar event, there are two methods: Calculated column, workflow. You can refer to:
A Simple Guide to Show More Information on a Calendar Event
I recommend to use workflow to achieve what you want. But you need to create a people column to display the manager.
You can create a workflow associated to the "Out of Office Request" list, add action to Start Approve Process. If the manager approves the request, you can create a item in the calendar, and then update the people column and the title column.
Then the calendar will display the Title, date/time and the manager.
To create a view for each manager, you need to modify the Filter. You can use the people column is equal to the manager name or the Title contains the manager name.
Thank you for your understanding.
Best Regards,

Data display issue in CF all non-IE browsers
The message title was a bit vague for all the factors
involved here so let me explain the problem in detail.
We are running ColdFusion 7, we use Oracle 9i and the
datatype of the field we are having issues with is a LONG field.
The data we are displaying is part of an application that has
an essay field. When we insert the data from the essay into the
Oracle 9i DB i can query the DB and get the correct result in SQL+
and Golden. The results are being stored as ASCII in the LONG
field. In IE displaying this data in any way works fine. However in
Firefox, Seamonkey, Opera or any other non-IE browser I've tested,
when I try to display the data in a text area or a text input even
I get a string filled with □. Also if I even try to output
the contents of the field in a cfoutput I cannot even copy the
string correctly, I only get the first letter.
So if i put in the essay field "Hello world" when I revisit
that page to edit it, it would look something like this
"H□e□l□l□o□
W□o□r□l□d□." I brought this into
ultraedit so I could try converting to see what exactly this
character represents (I had to view source, save the file and open
the saved file since copy and pasting is made impossible by
whatever is going on), and apparently the □ is the null
character.
[Edited: I am getting the null character in FF not in IE]
I am not entirely sure why I am getting a null character in
FF and not IE but I thought it might have something to do with the
fact that ColdFusion defaults to UTF-8 and the value is being
stored as ASCII. This is strange first off because I am not telling
CF to store the value to ASCII anywhere so you would think it would
default as UTF-8. Secondly I tried to force the page to default to
ASCII to see if that fixed the problem with <cfcontent
type="text/html; charset=us-ascii"> this would read the page as
ASCII but for some reason that field still comes in as UTF-8.
Bugged Display in
FCK editor
Bugged firefox
source of above display
Has anyone ever seen or heard of anything like this? It only
seems to happen with the LONG datatype because we have no issues on
any fields except fields that are LONG.
Thanks in advance for any assistance.Where does the data come from (FCK Editor, MS Word, other)?
This problem happens when I am using a text area, a text
input or FCK editor I submit the data via a form and allow the user
to edit it later if necessary using the same means (i.e. text
input, text area or FCKeditor). But this only occurs on fields that
insert to LONG datatypes. VARCHAR2's are working fine.
If you look at the data directly in the database does it look
fine?
Yes the data looks exactly as it should when I look at it in
the DB.
Have you tried something like this:
<cfprocessingdirective pageencoding="us-ascii">
Not yet, I will try that now and let you know how it works
What popped into my head was that somewhere the data is
double-byte
characters that are not using the second byte so it is null,
then later
on it is being interpreted as single-byte characters which is
exposing
the nulls.
I definately think this is the problem but I don't know
enough about encoding and how CF handles it to know how to fix the
problem.
I'll keep you all updated on my progress, thanks for the
suggestions thus far.

Want to combine the data different coloumn of table into single coloumn.
HI All ,
Requirement : I want to create an application which will display diffrent coloumn(data) of a table into single coloumn in web-dynpro abap .
For ex:
Table : employee
coloumn : PERSON , PAYMENT , STATUS , SUBMISSION .
RETURN = PAYMENT + STATUS + SUBMISSION
(return coloumn will contain the data of other coloumn )
Thanks in advance .
RahulIn your context, create a node 'Employee'. It should have the attributes person, payment, status, submission, return. Let return be of type string. I assume you have a ztable or some ddic structure employee, which does not have the return field.
You code will be on these lines - change it to your requirements anyway. Place the code in a method depending on your requirement of when the data should be displayed.
data: node_emp type ref to if_wd_context_node,
itab_emp type table of employee,
wa_emp type employee,
itab_node_emp type if_main=>elements_employee,
wa_node_emp type if_main=>element_employee.
node_emp = wd_context->get_child_node( name = 'EMPLOYEE' ).
<i>* Get data from your API here into itab_emp *</i>
loop at itab_emp into wa_emp.
move-corresponding wa_emp to wa_node_emp.
concatenate wa_emp-payment wa_emp-status wa_emp-submission separated by space into wa_node_emp-return.
append wa_node_emp to itab_node_emp.
endloop.
node_emp->bind_elements( itab_node_emp ).
Here, before the loop, you need to fetch the data into itab_emp using your APIs. Since you have said you want to display the data of multiple columns as is, I have just concatenated them.
In your view layout, have a table and bind the data source to be the context node Employee.
<b>The data types of itab_node_emp, wa_node_emp will differ based on your view name and node name. Use the code wizard to generate your code according to your design time.</b>
Hope this helps.

Video Playback in synchronization to data display
I've read a bunch of topics about recording live video, but my question has to do with playback synchronized to a data display. I've got a simple black and white camera (RS170) already. I'm going to get some sort of capture board. I want to record video from this camera to the hard drive. The reason is that this video file needs to be analyzed later so I need to store it on disk instead of memory as it could be days later. While I'm recording video, another signal needs to be recorded. It could be anything really, let us say temperature for discussion. Assume everything is in place for this temp. acquisition.
Recording video to disk doesn't seem to be any problem. My question relates to playing this video back such that when you play it, you can also look at a data display of the recorded temperatures that happened at the same time as the video was recorded. If you were to drag the video slider manually (instead of just pressing play), the data display would also update accordingly. This essentially syncs the data display of temperature with the video picture you are seeing. Pressing play and just watching the video, the temp data would update itself with the correct historical values. Pressing pause on the video, would of course freeze the temp display to the value at that time. Wherever the video is, the temp data would have to display the correct historical value.
I would need to record possibly a few hours of video a day so disk space could be an issue if using uncompressed AVI format. I wouldn't have to save every days video file so I could eventually delete a bunch of the files. I'd just save the days video that produces interesting results to examine later. A number of video files might build up (a months worth?) before the directory is examined for possible deletes. I'd like some feedback on this too from someone who has tried uncompressed AVI versus something else that is compressed. Is performance OK if using compression?
The computer I'd be running this on is the latest workstation class machine from HP so it is a fairly powerful computer.
Is there any sample code of doing this video playback indexing to data signal display? I'm thinking there would have to be some function to know where the video is playing at all times and then historically retrieve the temperature data. Is there performance issues with this? I'd want it fairly accurate such that the smallest increment of a video frame (say 30 times a second) produced a proper data display for temperature. In reality, my signal will change faster than a typical temperature value would.I doubt this will satisfy 100% of what you're looking for, but it should at least get the conversation started on developing some techniques we can use to syncronize acquired data playback (again, let's say temperature) with some external source. I don't know much about video playback, so I won't be able to help you much there, but I do know a lot about leveraging LabVIEW technology to play back data in real-time as best possible, while allowing the user (or the video playback itself) to dictate a specific position at any time, pause, etc...
My first recommendation would be to save your acquired temperature data as a Waveform. Waveform is more or less like a cluster with three elements: a 1D array of Y-values, an intial time (t0), and the time between samples (dt). You can use these three pieces of information to reconstitute when each sample was acquired and what the timing should be configured for to play these samples back in real time. Search the web for information on writing Waveforms to file and reading them. You should find plenty there (or post somewhere else ).
After that, we can use a Timed Loop for playback. Timed Loops allow you to set a desired Loop period. They also have a lot of other capabilities, such as setting priorities, handling the fact that your last loop didn't finish on time, etc. Here's a link with more info on Timed Loops. Other than that, Timed Loops can operate like regular while loops.
My next idea is to incorporate a current position that we keep track of. This could be, for instance, the index of the current element in the 1D Y-values array. If you want this to involve user interaction with the front panel (for instance, changing a Slider value to reflect the playback position), then you could use an event structure with a timeout case set to zero. Then update the temperature value and increment the current position in the timeout case.
You might take a look at the example I've written in LabVIEW 7.1 that "acquires" 5 seconds of sine wave data and plays it back in real time. The user can adjust the position or pause the playback at any time. Again, I don't know exactly how this would interface with video feedback. If you have more specifics about what method you will use to playback the video, maybe someone with more expertise in this area could help us out.

Validating Date parameter in discoverer
Hi
In the discoverer is it possible to validate or restrict the users to enter the wrong format of the date e.g. if the date format to be entered is dd-mm-yyyy, the system should not allow the users to enter mm-dd-yy,
Is it possible to put any validation?
As of now what is happening is discoverer is not telling me any thing after running for few minutes i am not getting any result, after that if i check i found that the date is in the wrong format
Regards
Ramesh Kumar SHi
If I may throw an aside in here. If your users are using 10.1.2 Plus there should be no need for users to key anything into any date parameter because Discoverer now has a calendar for this use. I find it much easier to teach my users to use a calendar than to try and teach them how to key dates in correctly.
One other thing you might want to consider if you have not already done so is to standardize a date format across your entire Discoverer installation. Then the date format will be obvious because its the same one they see all of the time.
Nevertheless, if you still want a mechanism to trap what users are keying it is possible to create functions that trap formats displaying appropriate error messages.
Best wishes

X and Y Data in scatter plot are different fields but can not be ??
When making a scatter plot with numbers you can select the X data in the series bar (X Value) then click tick then select the y data.
If I do this the initially entered X data becomes the Y data, if you do it vice-versa, the latter entry of y data becomes the X data.
I called up apple support for this issue and after explaining the a technical supervisor in their numbers section what a scatter plot was they said they’d put the issue in my file. Can someone fix this ……. ?
You need to be able to enter a number of different X, Y series of data where X is one column or a portion of that column and Y is a an identical number of rows to each x value but in a different column.
If apple’s wondering why this program’s not professionally used they might what to actually use it before releasing it.Rubin,
OK, you're using OSX Mavericks 10.9, and Numbers 3.0.1. It would be a good idea to update your profile to show the proper operating system version.
I think you are saying that you cant' add X-Y pairs to the chart as a new series. Apple has switched the default. Scatter Charts used to default to adding pairs of columns representing new X-Y pairs, but now it defaults to the mode called Share X-Axis values, so it thinks you are adding 2 new sets of Y-values sharing the first column of x-values.
The switch for this is in the lower left corner of the Numbers window. This control used to be in the upper left of the chart range indicator in the source table, but they moved it. Click on the "Plot Columns as Series" button to reveal the menu. Then un-check Share X Values.
