Need help with AcqVoltageSamples_IntClkAnalogStart example

When running this VB.NET example without any modifications, I get this error:
Property: NI.DAQmx.StartTrigger.Type
You have requested: ...AnalogEdge
You can select: DigitalEdge, None
Out of the box, the example specifies trigger source PFI0.
What do I need to do for this example to run?
Thanks.

Usually, this error indicates that the DAQ card you are using does not support triggering on an analog signal. Since our DAQ cards that do support analog triggers can trigger on PFI0, this is probably your problem. If you have a digital signal to use for your trigger, change the "task.Triggers.StartTrigger.ConfigureAnalogEdgeTrigger" call in the example to call "task.Triggers.StartTrigger.ConfigureDigitalEdgeTrigger". If you need trigger on an analog signal, I would contact your sales engineer about replacing your card with one that has the necessary analog trigger circuitry.

Need help with Berkeley XML DB Performance

We need help with maximizing performance of our use of Berkeley XML DB. I am filling most of the 29 part question as listed by Oracle's BDB team.
Berkeley DB XML Performance Questionnaire
1. Describe the Performance area that you are measuring? What is the
current performance? What are your performance goals you hope to
achieve?
We are measuring the performance while loading a document during
web application startup. It is currently taking 10-12 seconds when
only one user is on the system. We are trying to do some testing to
get the load time when several users are on the system.
We would like the load time to be 5 seconds or less.
2. What Berkeley DB XML Version? Any optional configuration flags
specified? Are you running with any special patches? Please specify?
dbxml 2.4.13. No special patches.
3. What Berkeley DB Version? Any optional configuration flags
specified? Are you running with any special patches? Please Specify.
bdb 4.6.21. No special patches.
4. Processor name, speed and chipset?
Intel Xeon CPU 5150 2.66GHz
5. Operating System and Version?
Red Hat Enterprise Linux Relase 4 Update 6
6. Disk Drive Type and speed?
Don't have that information
7. File System Type? (such as EXT2, NTFS, Reiser)

8. Physical Memory Available?
4GB
9. Are you using Replication (HA) with Berkeley DB XML? If so, please
describe the network you are using, and the number of Replica’s.
No
10. Are you using a Remote Filesystem (NFS) ? If so, for which
Berkeley DB XML/DB files?
No
11. What type of mutexes do you have configured? Did you specify
–with-mutex=? Specify what you find inn your config.log, search
for db_cv_mutex?
None. Did not specify -with-mutex during bdb compilation
12. Which API are you using (C++, Java, Perl, PHP, Python, other) ?
Which compiler and version?
Java 1.5
13. If you are using an Application Server or Web Server, please
provide the name and version?
Oracle Appication Server 10.1.3.4.0
14. Please provide your exact Environment Configuration Flags (include
anything specified in you DB_CONFIG file)
Default.
15. Please provide your Container Configuration Flags?
final EnvironmentConfig envConf = new EnvironmentConfig();
envConf.setAllowCreate(true); // If the environment does not
// exist, create it.
envConf.setInitializeCache(true); // Turn on the shared memory
// region.
envConf.setInitializeLocking(true); // Turn on the locking subsystem.
envConf.setInitializeLogging(true); // Turn on the logging subsystem.
envConf.setTransactional(true); // Turn on the transactional
// subsystem.
envConf.setLockDetectMode(LockDetectMode.MINWRITE);
envConf.setThreaded(true);
envConf.setErrorStream(System.err);
envConf.setCacheSize(1024*1024*64);
envConf.setMaxLockers(2000);
envConf.setMaxLocks(2000);
envConf.setMaxLockObjects(2000);
envConf.setTxnMaxActive(200);
envConf.setTxnWriteNoSync(true);
envConf.setMaxMutexes(40000);
16. How many XML Containers do you have? For each one please specify:
One.
1. The Container Configuration Flags
          XmlContainerConfig xmlContainerConfig = new XmlContainerConfig();
          xmlContainerConfig.setTransactional(true);
xmlContainerConfig.setIndexNodes(true);
xmlContainerConfig.setReadUncommitted(true);
2. How many documents?
Everytime the user logs in, the current xml document is loaded from
a oracle database table and put it in the Berkeley XML DB.
The documents get deleted from XML DB when the Oracle application
server container is stopped.
The number of documents should start with zero initially and it
will grow with every login.
3. What type (node or wholedoc)?
Node
4. Please indicate the minimum, maximum and average size of
documents?
The minimum is about 2MB and the maximum could 20MB. The average
mostly about 5MB.
5. Are you using document data? If so please describe how?
We are using document data only to save changes made
to the application data in a web application. The final save goes
to the relational database. Berkeley XML DB is just used to store
temporary data since going to the relational database for each change
will cause severe performance issues.
17. Please describe the shape of one of your typical documents? Please
do this by sending us a skeleton XML document.
Due to the sensitive nature of the data, I can provide XML schema instead.
18. What is the rate of document insertion/update required or
expected? Are you doing partial node updates (via XmlModify) or
replacing the document?
The document is inserted during user login. Any change made to the application
data grid or other data components gets saved in Berkeley DB. We also have
an automatic save every two minutes. The final save from the application
gets saved in a relational database.
19. What is the query rate required/expected?
Users will not be entering data rapidly. There will be lot of think time
before the users enter/modify data in the web application. This is a pilot
project but when we go live with this application, we will expect 25 users
at the same time.
20. XQuery -- supply some sample queries
1. Please provide the Query Plan
2. Are you using DBXML_INDEX_NODES?
Yes.
3. Display the indices you have defined for the specific query.
     XmlIndexSpecification spec = container.getIndexSpecification();
     // ids
     spec.addIndex("", "id", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     spec.addIndex("", "idref", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // index to cover AttributeValue/Description
     spec.addIndex("", "Description", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_SUBSTRING, XmlValue.STRING);
     // cover AttributeValue/@value
     spec.addIndex("", "value", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // item attribute values
     spec.addIndex("", "type", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // default index
     spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // save the spec to the container
     XmlUpdateContext uc = xmlManager.createUpdateContext();
     container.setIndexSpecification(spec, uc);
4. If this is a large query, please consider sending a smaller
query (and query plan) that demonstrates the problem.
21. Are you running with Transactions? If so please provide any
transactions flags you specify with any API calls.
Yes. READ_UNCOMMITED in some and READ_COMMITTED in other transactions.
22. If your application is transactional, are your log files stored on
the same disk as your containers/databases?
Yes.
23. Do you use AUTO_COMMIT?
     No.
24. Please list any non-transactional operations performed?
No.
25. How many threads of control are running? How many threads in read
only mode? How many threads are updating?
We use Berkeley XML DB within the context of a struts web application.
Each user logged into the web application will be running a bdb transactoin
within the context of a struts action thread.
26. Please include a paragraph describing the performance measurements
you have made. Please specifically list any Berkeley DB operations
where the performance is currently insufficient.
We are clocking 10-12 seconds of loading a document from dbd when
five users are on the system.
getContainer().getDocument(documentName);
27. What performance level do you hope to achieve?
We would like to get less than 5 seconds when 25 users are on the system.
28. Please send us the output of the following db_stat utility commands
after your application has been running under "normal" load for some
period of time:
% db_stat -h database environment -c
% db_stat -h database environment -l
% db_stat -h database environment -m
% db_stat -h database environment -r
% db_stat -h database environment -t
(These commands require the db_stat utility access a shared database
environment. If your application has a private environment, please
remove the DB_PRIVATE flag used when the environment is created, so
you can obtain these measurements. If removing the DB_PRIVATE flag
is not possible, let us know and we can discuss alternatives with
you.)
If your application has periods of "good" and "bad" performance,
please run the above list of commands several times, during both
good and bad periods, and additionally specify the -Z flags (so
the output of each command isn't cumulative).
When possible, please run basic system performance reporting tools
during the time you are measuring the application's performance.
For example, on UNIX systems, the vmstat and iostat utilities are
good choices.
Will give this information soon.
29. Are there any other significant applications running on this
system? Are you using Berkeley DB outside of Berkeley DB XML?
Please describe the application?
No to the first two questions.
The web application is an online review of test questions. The users
login and then review the items one by one. The relational database
holds the data in xml. During application load, the application
retrieves the xml and then saves it to bdb. While the user
is making changes to the data in the application, it writes those
changes to bdb. Finally when the user hits the SAVE button, the data
gets saved to the relational database. We also have an automatic save
every two minues, which saves bdb xml data and saves it to relational
database.
Thanks,
Madhav

Could it be that you simply do not have set up indexes to support your query? If so, you could do some basic testing using the dbxml shell:
milu@colinux:~/xpg > dbxml -h ~/dbenv
Joined existing environment
dbxml> setverbose 7 2
dbxml> open tv.dbxml
dbxml> listIndexes
dbxml> query     { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }
dbxml> queryplan { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }Verbosity will make the engine display some (rather cryptic) information on index usage. I can't remember where the output is explained; my feeling is that "V(...)" means the index is being used (which is good), but that observation may not be accurate. Note that some details in the setVerbose command could differ, as I'm using 2.4.16 while you're using 2.4.13.
Also, take a look at the query plan. You can post it here and some people will be able to diagnose it.

Need help with almost completed plugin engine project

Hi all,
For a while now I have been working on a plugin engine. After a few iterations, the engine is similar to the Eclipse engine, in that plugins use extension points and extensions to allow contributions. Unlike the eclipse engine I have added the ability for plugins to fire events through the engine and other plugins can add listeners, all through the plugin.xml manifest. Dependencies are mostly handled automatically at plugin load time (when extensions get resolved to extension points, and listeners get resolved to events). For the case where a plugin needs to use classes from another plugin, dependencies are also allowed to be declared. Like the eclipse engine, activation of plugins occurs the first time a class is used within the plugin's classpath, OR a plugin can be activated after it is loaded.
What I need help with is testing, working on examples to provide with the engine project, and feedback/suggestions before we release the M1 build. I am asking for those that are interested in this type of work to volunteer to help where applicable and possible. I want to provide a solid plugin engine to the java community, one that is easy to use, works well, and is pretty effecient in terms of resource usage and performance.
Of particular interest to me right at the moment is dealing with multiple versions. As I see it, the engine will be used within an application and as such plugins would be distributed with a specific application version. The plugin version itself is more of a notification as to what version a plugin is, although I imagine it will help when updating at runtime as well.
Just a few other details of the engine. It handles (or will soon) dynamic load, unload and reload of plugins at runtime. Plugins can be distributed in an archive file format, we call .par (Plugin ARchive), with additional plugin filename extensions configurable at runtime. The plugins can be developed and deployed in an expanded directory format as they are in Eclipse as well, or in the archive format. In the archive format they do not need to be unzipped when deployed, and they can contain embeded jar/zip libraries. The engine handles finding and creating classes directly out of the .par file at runtime.
Multiple locations to find plugins are configurable before the engine starts, and even after it starts more could be added to allow additional locations to find plugins. URLs are supported, and soon the HTTP protocol will be supported so that plugins can be downloaded and installed at runtime.
The project can be found at www.sourceforge.net/projects/genpluginengine. If you would like to get involved and help out, please sign up on the dev mail list and send an email to introduce yourself to the rest of the members on the list.
I'll also add that I am working on a Swing UI Framework built entirely from plugins. It provides a ready-to-launce UI application that developers can simply add their plugins to, extending various extension points of the framework to have menu items, toolbar buttons, status bar access, help and preferences dialog additions, file i/o choosers, tons of open-source components ready to use (or extend to add on to), and like Eclipse, hopefully... draggable window frames that can be dropped on any other frame to form a tabbed frame of windows. Some of this is a ways off, some is getting there now. Presently you can add menu items that do allow plugin activation when first clicked, so plugins can be loaded but not activated until needed. The Preference dialog works but is not completed, and a plugin that adds a plugin control panel to view all loaded plugins, activate them, load/unload/reload, view extension points, extensions, dependencies, etc is partially completed. The point is, to allow a ready to run UI framework in Swing with an easy path for developers to quickly build applications with. If you are interested in this, when you join the mail list and introduce yourself, indicate that you are interested in this as well, as we need help with plugin development for it and would appreciate more help here too.
Look forward to some replies.

Might I suggest setting up a project at a known project-site? I've seen your progress and questions posted here from time to time, but one of the drawbacks is that you have to fill each post with the entirity of your vision to explain what you're doing. That's a lot of text to read - and most folks will skip right over it.
On the other hand, a well-crafted, good-looking project web-site, with appropriate links and docs and vision statements, diagrams, etc. will have more likelyhood of attracting volunteers. java.net and sourceforge.net are likely spots to set up shop. In addition, you get CVS and bug-tracking systems, which can be quite valuable in such a large-scale project where there are lots of pieces.

Need help with a simple process with FTP Adapter and File Adapter

I am trying out a simple BPEL process that gets a file in opaque mode from a FTP server using a FTP adapter and writes it to the local file system using a File Adapter. However, the file written is always empty (zero bytes). I then tried out the FTPDebatching sample using the same FTP server JNDI name and this work fine surprisingly. I also verified by looking at the FTP server logs that my process actually does hit the FTP server and seems to list the files based on the filtering condition - but it does not issue any GET or RETR commands to actually get the files. I am suspecting that the problem could be in the Receive, Assign or Invoke activities, but I am not able identify what it is.
I can provide additional info such as the contents of my bpel and wsdl files if needed.
Would appreciate if someone can help me with this at the earliest.
Thanks

I need help with event structure.
I am trying to feed the index of the array, the index number can vary from 0 to 7.
Based on the logic ouput of a comparison, the index buffer should increment
or decrement every time the output of comparsion changes(event change). I guess I need to use event structure?
(My event code doesn't execute when there is an event at its input /comparator changes its boolean state.
Anyone coded on similar lines? Any ideas appreciated.
Thanks in advance!

You don't need an Event Structure, a simple State Machine would be more appropriate.
There are many examples of State Machines within this forum.

Need Help with Address Display

I need help with APEX.
Here's my situation:
I have a report that displays brief employee information. Among the information displayed is the Address. Right now, it's display as:
Mr X
Employee Id
Accounting Department
Address 1
Mr X
Employee Id
Accounting Department
Address 2
I would like it to display
Mr X
Employee Id
Accounting Department
Address 1
Address 2
1) I have thought of using the Break functionality; however, the function only allows break at column 1, 2, 3. As you can see Address starts at column 4. Also, Address has a few columns; Address Line 1, Address Line 2, City, State, Zipcode.
2) Stragg functions - I'm not sure how to implement it since it has more than 1 columns.
Any ideas?
Thanks in advance
Andrew

The example I gave you, using analytic functions is a simple one.
Now, you are saying:
1. some of the employees may have two adresses?
2. if this is the case, your employee appears in the report twice?
3. you don't want his name, employee id and accounting department to appear twice?
4. only his address has to be displayed?
If the answer to all the questions is yes, this kind of query will help you. I repeat:
SELECT CASE
          WHEN LAG (employee_id) OVER (ORDER BY employee_id) =
                                                    employee_id
             THEN NULL
          ELSE employee_name
       END employee_name,
       CASE
          WHEN LAG (employee_id) OVER (ORDER BY employee_id) =
                                                      employee_id
             THEN NULL
          ELSE employee_id

                                            employee_id
             THEN NULL
          ELSE accounting_department
       END accounting_department,

Need help with a terminal command

Ever since Lion, or maybe even earlier, I am fighting a losing battle against memory leaks on my MacBook Pro. Safari for example takes over time 2GB+ for just 2 or 3 tabs open with almost no extensions active. Really strange.
Someone told me about the "purge" command in Terminal to free some of the sequestered memory, so I am doing this a few times a day to be able to use Photoshop, Keynote, Premiere and other stuff concurrently without opening and closing apps like I did 10 or 15 years ago, remember those days?
So here are my 2 questions:
Will this frequent "purge" command harm anything in the long run?
If no, is it possible to automate this "purge" Terminal action somehow? Maybe a desktop icon to click, or fully automated? I am a designer, not a coder, so I would need help with that.
Thank you for your input!

Need help with writing a rule

Need help with some rules. I want to book a number to a specific Entity at a Specific Custom 4 only. I don't want this formula to work at all C4 levels. How can this be done?
for example if Entity is "XBM1123" and we use C4 for tracking and the tracking level I want to book it to is IMPORT, how can this be done for a specific account 4400221
I have my formula as
If pov_value = "<Entity Currency>" or pov_value = "<Entity Curr Adjs>" Then
If HS.Entity.Member = "XBM1123" or HS.Custom4.Member = "IMPORT" then
HS.EXP "A#4400221= A#4521111 + A#3526644 + A#635210"
End If
End if
this did not work. I got hte following error
Calculate started.<BR>Error executing VBScript Microsoft VBScript runtime
error, Line 259:Object doesn't support this property or method:
'HS.Custom4.Member'.<BR>Calculate finished.<BR>Error executing
VBScript %0.
I then changed it to the below and it still did not work
If pov_value = "<Entity Currency>" or pov_value = "<Entity Curr Adjs>" Then
If HS.Entity.Member = "XBM1123" then
HS.EXP "A#4400221.C4#IMPORT= A#4521111 + A#3526644 + A#635210"
End If
End if
error
Invalid Custom1 member
specified for this function.
Invalid Destination specified for this function:
A#4400221.C4#IMPORT.

You are close.
Try:
If pov_value = "<Entity Currency>" or pov_value = "<Entity Curr Adjs>" Then
    If HS.Entity.Member = "XBM1123" then
       HS.EXP "A#4400221.C4#IMPORT= A#4521111.C4#IMPORT + A#3526644.C4#IMPORT + A#635210.C4#IMPORT"
    End If
End if
or replace IMPORT with with Top_C4 or what ever member you need to copy to C4#IMPORT.
Rule of thumb, to be on the safe side and for most simple calcs, is if you mention a dimension on the left side, you need to define it on the right side as well.

Need help with Page Layout and Background Scaling

hello, everyone.
I am in the process of designing a new website for myself,
and while I was researching nicely designed pages to use as
inspiration, I stumbled upon this site:
http://www.jeffsarmiento.com/
obviously, the design is very impressive, but it also
incorporates a lot of web mechanics that I have been trying to
figure out, so I will use this page as an example.
one thing I need help with is backgrounds. as you can see in
the posted website, the creator used a seamlessly tiled paper
texture to display the bulk of his content on. also make not of the
pattern that is located to the left of the paper texture. how do I
create seamless backgrounds like this that will scale to fit any
amount of content or any resolution? I can't imagine that the guy
that made that site created a new size background every time he
made an update, so there has to be an easier way.
the second thing that I am having trouble with is general
site layout. I have read that most sites used series of invisible
tables to organize there content, but when I open the source of
this page in dreamweaver, he was using something different. div
tags? should I be using these? who do I use them? are there any
general layout tips that someone could pass on to me? perhaps a
link to a good tutorial?
please help me. i am very confused.
thanks so much.

IMO not a good site to emulate. To wit:
Top background image:

Main background image:

745px x 950px 130K
Total page size: 454K (Check here:
www.websiteoptimization.com)
Website usability experts routinely recommend a maximum page
size of ~80K
Check out the We We Scale @ www.FutureNowInc.com/wewe/ where
they suggest,
"You speak about yourself approximately 0,003 times as often
as you speak
about your customers. Might that have an impact on your
effectiveness?"
That is 100% consistent with the #1 Web Design mistake:
"Believing people
care about you and your web site." or to phrase more
expansively, "Our site
tries to tell you how wonderful we are as a company, but not
how we're going
to solve your problems."
www.sitepoint.com has some excellent books on making a
website actually
attractive and usable at the same time.

Need help with the session state value items.

I need help with the session state value items.
Trigger is created (on After delete, insert action) on table A.
When insert in table B at least one row, then trigger update value to 'Y'
in table A.
When delete all rows from a table B,, then trigger update value to 'N'
in table A.
In detail report changes are visible, but the trigger replacement value is not set in session value.
How can I implement this?

You'll have to create a process which runs after your database update process that does a query and loads the result into your page item.
For example
SELECT YN_COLUMN
FROM My_TABLE
INTO My_Page_Item
WHERE Key_value = My_Page_Item_Holding_Key_ValueThe DML process will only return key values after updating, such as an ID primary key updated by a sequence in a trigger.
If the value is showing in a report, make sure the report refreshes on reload of the page.

Project Server 2013: I am using Project Server Permission Mode and need help with permission assignments?

Hi
Project Server 2013: I am using Project Server Permission Mode and need help with permission assignments?
How can I change Permissions for the individual users to see specific projects or all projects in project center and to see specific quick launch items?
For Example: if i have 4 users, A, B, C and D. what i want is:
User A can see everything and act as a project manager or Admin.
User B can view all projects in project centre but can change the schedule or resource assignment etc.
User C can only act as approver of projects and can view all projects in project centre.
User D can only view specific projects for which permissions are given.
can i have some expert help in sorting and understanding permission modes... as i was playing with project server mode permissions and can't figure out how to apply the above scenario to set of my user.
Thanks in Advance
Cheers

Hi Ajay,
Please refer to this link for detailed explanations about PS2013 security model.
http://technet.microsoft.com/en-us/library/cc197638(v=office.15).aspx
Actually, it will take a couple of days to explain in detail the security model that is a fundamental and tricky aspect of every PS implementation. But basically, you NEVER set permissions for a single user. You have groups in which your insert users. Groups
define "what users can do". Then you associate groups to a corresponding category. Categories define "what user can see". Thus the association of a group with a category will set "what the user can do on the objects he can see". Then, for more advanced security
level, you can use the RBS that will consist in "branches" in which you'll insert users. Based on those branches, you'll customize categories to fine-tune what user can see (for projects and resources) depending on the RBS branch and level.
I'd advice you to start "playing" in a test environment with the default categories/groups that might probably cover your need.
Concerning your 4 users:
user A : add him to the "administrator" group. Be careful that you're mentionning either project manager or administrator, which are 2 groups/categories with totally different permissions level.
user B : basically can see everything and change everything? it could be in the project manager group, assuming that there are no project visibility restrictions on the category via the RBS.
user C : waht do you mean by "approver"? Workflow approvals? Then it will be the portfolio manager group. Task update or timesheet approval? Then it is another long topic: please refer in the documentation to the "status manager" and "timesheet manager"
concepts. There are not related to the security model. In a few words, the status manager is the owner of the project plan, is defined for each task and approves tasks updates. The timesheet manager is an attribute defined for each resource in its parameters
and approves resource timesheet.
user D : you have to define which permission level must be given to this user. Basically it could be a team member that will see only projects he's in the project team. Note that team member cannot interact with the project plan in another way than submitting
timesheets and/or tasks updates which must be approved.
Once more, those are large and complex subjects that require a deep dive into your business model and tons of tests in a test environment.
Hope this helps.

I need help with a SELECT query - help!

Hello, I need help with a select statement.
I have a table with 2 fields as shown below
Name | Type
John | 1
John | 2
John | 3
Paul | 1
Paul | 2
Paul | 3
Mark | 1
Mark | 2
I need a query that returns everything where the name has type 1 or 2 but not type 3. So in the example above the qery should bring back all the "Mark" records.
Thanks,
Ian

Or, if the types are sequential from 1 upwards you could simply do:-
SQL> create table t as
2 select 'John' as name, 1 as type from dual union
3 select 'John',2 from dual union
4 select 'John',3 from dual union
5 select 'Paul',1 from dual union
6 select 'Paul',2 from dual union
7 select 'Paul',3 from dual union
8 select 'Paul',4 from dual union
9 select 'Mark',1 from dual union
10 select 'Mark',2 from dual;
Table created.
SQL> select name
2 from t
3 group by name
4 having count(*) <= 2;
NAME
Mark
SQL>Or another alternative if they aren't sequential:
SQL> ed
Wrote file afiedt.buf
1 select name from (
2    select name, max(type) t
3    from t
4    group by name
5    )
6* where t < 3
SQL> /
NAME
Mark

Need help with writing a query with dynamic FROM clause

Hi Folks,
I need help with an query that should generate the "FROM" clause dynamically.
My main query is as follows
select DT_SKEY, count(*)
from *???*
where DT_SKEY between 20110601 and 20110719
group by DT_SKEY
having count(*) = 0
order by 1; The "from" clause of the above query should be generated as below
select 'Schema_Name'||'.'||TABLE_NAME
from dba_tables
where OWNER = 'Schema_Name'Simply sticking the later query in the first query does not work.
Any pointers will be appreciated.
Thanks

Remember that anything inside quotes is case-sensitive. Is the owner really "Schema_Name" with a capital S and a capital N, and 8 lower-case letters?
Simply sticking the later query in the first query does not work.Right; the table name must be given when you compile the query. It's not an expression that you can generate in the query itself.
Any pointers will be appreciated.In SQL*Plus, you can do something like the query bleow.
Say you want to count the rows in scott.emp, but you're not certain that the name is emp; it could be emp_2011 or emp_august, or anything else that starts with e. (And the name could change every day, so you can't just look it up now and hard-code it in a query that you want to run in the future.)
Typically, how dynamic SQL works is that some code (such as a preliminary query) gets some of the information you need to write the query first, and you use that information in a SQL statement that is compiled and run after that. For example:
-- Preliminary Query:
COLUMN     my_table_name_col     NEW_VALUE my_table_name
SELECT     table_name     AS my_table_name_col
FROM     all_tables
WHERE     owner          = 'SCOTT'
AND     table_name     LIKE 'E%';
-- Main Query:
SELECT     COUNT (*)     AS cnt
FROM     scott.&my_table_name
;This assumes that the preliminary query will find exactly one row; that is, it assumes that SCOTT has exactly one table whose name starts with E. Could you have 0 tables in the schema, or more than 1? If so, what results would you want? Give a concrete example, preferably suing commonly available tables (like those in the SCOTT schema) so that the poepl who want to help you can re-create the problem and test their ideas.

Need Help With D&D Program

Hi, I'm not sure if I'm allowed to post questions on this forum but I can't find anywhere to talk to helpful people about programming.
I'm making a dnd interface for JComponents. So far I've made a simple program that has a Component that can be lifted from a container and braught to the glass pane then later moved to anywhere on the screen and dropped into the container below it. Here's where my problems come:
1) Rite now my 'Movable Component' is a JPanel which is just colored in. I want to either take a Graphic2d from a JComponent/Component and draw it on the JPanel or change the JPanel to the component I want to paint and disable the component.
The problem with getting the Graphics2d is that if the component isn't on the screen it doesn't make a graphic object. I tried messing with the ui delicate and overriding parental methods for paintComponent, repaint, and that repaintChildren(forget name) but I haven't had luck getting a good graphics object. I was thinking of, at the beginning of running the program, putting 1 of each component onto the screen for a second then removing it but I'd rather not. I'd also like to change the graphics dynamicly if someone stretches the component there dropping and what not.
The problem with disabling is that it changes some of the visual features of Components. I want to be able to update the Component myself to change how it looks and I don't want disabling to gray out components.
I mainly just dont want the components to do any of there normal fuctions. This is for a page builder, by the way.
Another problem I'm having is that mouseMotionListener is allowing me to select 2 components that are on top of one another when there edges are near each other. I don't know if theres a fix to this other than changing the Java Class.
My next problem is a drop layout manager, but I'm doing pretty good with that rite now. It'll problem just move components out of the way of the falling component.
One last thing I need help with is that I don't want the object that's being carried to go across the menu bar and certain areas. When I'm having the object being carried I have it braught up to the glass pane which allows it to move anywhere. Does anyone have any idea how I could prevent the component from being over the menu bars and other objects? I might have to make 1 panel is the movable area that can then be broken down into the 'component bank', 'building page' and whatever else I'm gonna need.
This is all just test code to get together for when I make the real program but I need to make sure it'll be possible without a lot of hacking of code.
Sorry for the length. Thanks for any help you can give.

The trick to making viewable components that have no behaviour, is to render them onto an image of some sort (eg a BufferedImage). You can then display the Image on a JLabel that can be dragged around the desktop.
Here is a piece of code that does the component rendering for you. This particular example uses a fixed component size, but you can modify that as you choose of course...public class JComponentImage
     private static GraphicsConfiguration gConfig;
     private static Dimension compSize = new Dimension(80, 22);
     private static Image image = null;
     public static Image getImage(Class objectClass)
          if (gConfig == null)
               GraphicsEnvironment gEnv = GraphicsEnvironment.getLocalGraphicsEnvironment();
               GraphicsDevice gDevice = gEnv.getDefaultScreenDevice();
               gConfig = gDevice.getDefaultConfiguration();
          image = gConfig.createCompatibleImage(compSize.width, compSize.height);
          JComponent jc = (JComponent) ObjectFactory.instantiate(objectClass);
          jc.setSize(compSize);
          Graphics g = image.getGraphics();
          g.setColor(Color.LIGHT_GRAY);
          g.fillRect(0, 0, compSize.width, compSize.height);
          g.setColor(Color.BLACK);
          jc.paint(g);
          return image;
}And here is the class that makes the dragable JLabel using the class above...public class Dragable extends JLabel
     private static DragSource dragSource = DragSource.getDefaultDragSource();
     private static DragGestureListener dgl = new DragMoveGestureListener();
     private static TransferHandler th = new ObjectTransferHandler();
     private Class compClass;
     private Image image;
     Dragable(Class compClass)
          this.compClass = compClass;
          image = JComponentImage.getImage(compClass);
          setIcon(new ImageIcon(image));
          setTransferHandler(th);
          dragSource.createDefaultDragGestureRecognizer(this,
                                                      DnDConstants.ACTION_COPY,
                                                      dgl);
     public Class getCompClass()
          return compClass;
}Oh and here is ObjectFactory which simply instantiates Objects of a given class and sets their text to their classname (very crudely)...public class ObjectFactory
     public static Object instantiate(Class objectClass)
          Object o = null;
          try
               o = objectClass.newInstance();
          catch (Exception e)
               System.out.println("ObjectFactory#instantiate: " + e);
          String name = objectClass.getName();
          int lastDot = name.lastIndexOf('.');
          name = name.substring(lastDot + 1);
          if (o instanceof JLabel)
               ((JLabel)o).setText(name);
          if (o instanceof JButton)
               ((JButton)o).setText(name);
          if (o instanceof JTextComponent)
               ((JTextComponent)o).setText(name);
          return o;
}Two more classes required by this codepublic class ObjectTransferHandler extends TransferHandler {
     private static DataFlavor df;
      * Constructor for ObjectTransferHandler.
     public ObjectTransferHandler() {
          super();
          try {

          Transferable t = null;
          try {
               t = new ObjectTransferable(((Dragable) jC).getCompClass());
          } catch (Exception e) {
               Debug.trace(e.toString());
          return t;
     public int getSourceActions(JComponent c) {
          return DnDConstants.ACTION_MOVE;
     public boolean canImport(JComponent comp, DataFlavor[] flavors) {
          if (!(comp instanceof Dragable) && flavors[0].equals(df))
               return true;
          return false;
     public boolean importData(JComponent comp, Transferable t) {

          try {
               c = (JComponent) t.getTransferData(df);
          } catch (Exception e) {
               Debug.trace(e.toString());
          comp.add(c);
          comp.validate();
          return true;
public class ObjectTransferable implements Transferable {

          try {
               df = new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType);
          } catch (ClassNotFoundException e) {

     public Object getTransferData(DataFlavor arg0)
          throws UnsupportedFlavorException, IOException {

}And of course the test class:public class DragAndDropTest extends JFrame
     JPanel leftPanel = new JPanel();
     JPanel rightPanel = new JPanel();
     Container contentPane = getContentPane();
     Dragable dragableJLabel;
     Dragable dragableJButton;
     Dragable dragableJTextField;
     Dragable dragableJTextArea;
      * Constructor DragAndDropTest.
      * @param title
     public DragAndDropTest(String title)
          super(title);
          dragableJLabel = new Dragable(JLabel.class);
          dragableJButton = new Dragable(JButton.class);
          dragableJTextField = new Dragable(JTextField.class);
          dragableJTextArea = new Dragable(JTextArea.class);
          leftPanel.setBorder(new EtchedBorder());
          BoxLayout boxLay = new BoxLayout(leftPanel, BoxLayout.Y_AXIS);
          leftPanel.setLayout(boxLay);
          leftPanel.add(dragableJLabel);
          leftPanel.add(dragableJButton);
          leftPanel.add(dragableJTextField);
          leftPanel.add(dragableJTextArea);
          rightPanel.setPreferredSize(new Dimension(500,500));
          rightPanel.setBorder(new EtchedBorder());
          rightPanel.setTransferHandler(new ObjectTransferHandler());
          contentPane.setLayout(new BorderLayout());
          contentPane.add(leftPanel, "West");
          contentPane.add(rightPanel, "Center");
     public static void main(String[] args)
          JFrame frame = new DragAndDropTest("Drag and Drop Test");
          frame.pack();
          frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
          frame.setVisible(true);
}I wrote this code some time ago, so it won't be perfect but hopefully will give you some good ideas.
