Labview signalexpress extract part of the data

Hi, I'm using signalexpress 2.0 and I was wondering how I can take data I've recorded and remove parts to leave with with just a certain bit I'm interested in.

Use the Subset and Resample step with the full data as an input. You don't have to resample.

Extracting Year from the date field

Hi,
I want to extract year from the date field... I've tried following code but got the error
SELECT to_char(a.A_EXPIRY_DATE,'yyyy') as EXP_YEAR from Table_A a
Please advice
Thanks in advance

What error did you get?
maybe your column name is wrong? Is it really A_somthing? This is possible but slightly unusual.
also possible
select extract(Year from sysdate) from dual;
/* with your table and column */

Fetch part of the data in an announcement posting for summary display

I have a request from user to extract a paragraph of content from announcement web part and to display the content to another page.
The query of the extraction is to extract the annoucement that is posted for day. Once the summary is generated, an email will be sent out to users with the extracted data.
How can i have part of the content of each announcement extracted using c# in visual studio 2013?

May be you can plan to extract all the data from list and then filter the content you are looking for
http://stackoverflow.com/questions/490968/how-do-you-read-sharepoint-lists-programatically
You have several options both of which are going to require further research on your part they are:
Use the SharePoint object model (Microsoft.Sharepoint.dll), you must be on a PC within the SharePoint farm.
Use the SharePoint web services which can be found at SiteURL/_vti_bin/ you might want to start with Lists.asmx and work from there.
You are going to need some further research as I have said, but remember GIYF.

Using INSTR to extract part of the string ?

Morning guys and Happy Friday.
I have a situation where I have to pull out part of the string using a select statement.
Here is the string and I have to get the contents between the 2nd and 3rd backslash. So, basically, I have to extract marypoppins. Any ideas ?
C:\USERS\marypoppins\Docs\SpecificationHere is where I started ... and I have stumbled upon trying to find the 3rd backslash. I can easily start the INSTR at 4 because I know that it will always be 'C:\'
select select substr(C:\USERS\marypoppins\Docs\Specification',
                            INSTRB('C:\USERS\marypoppins\Docs\Specification', '\', 4), .....) from dual;

Additionally you can break it all up simply with regular expressions..
SQL> ed
Wrote file afiedt.buf
1 with t as (select 'C:\USERS\marypoppins\Docs\Specification' as txt from dual)
2 -- END OF TEST DATA
3 select rownum, regexp_substr(txt, '[^\]+',1,rownum) as element
4 from t
5* connect by rownum <= length(regexp_replace(txt,'[^\]'))+1

Data flows are getting started but not completing successfully while extracting/loading of the data

Hello People,
We are facing a abnormal behavior with the dataflows in the data services job.
Scenario:
We are extracting the data from CRM end in parallel. Please refer the build:
a. We have 5 main workflows flows i.e :
   => Main WF1 has 6 more sub Wf's in it, in which each sub Wf has 1/2 DF's associated in parallel.
   => Main WF2 has 21 DF's and 1 WFa->with a DF & a WFb. WFb has 1 DF in parallel.
   => Main WF3 has 1 DF in parallel.
   => Main WF4 has 3 DF in parallel.
   => Main WF5 has 1 WF & a DF in sequence.
b. Regularly the job works perfectly fine but, sometimes it gets stuck at the DF’s without any error logs.
c. Job doesn’t stuck at a specific dataflow or on a specific day, many a times it strucks at different DF’s.
d. Observations in the Monitor Log:
Dataflow---------------------- State----------------RowCnt------LT-------AT------
+DF1/ZABAPDF
PROCEED
234000
8.113      394.164
/DF1/Query
PROCEED
234000
8.159      394.242
-DF1/Query_2
PROCEED
234000
8.159      394.242
Where LT: Lapse Time and AT: Absolute time
If you check the monitor log, the State of the Dataflow DF1 remains PROCEED till the end, ideally it should complete.
In successful jobs, the status for DF1 is STOP . This DF takes approx. 2 min to execute.
The row count for DF1 extraction is 234204 but, it got stuck at 234000.
Then we terminate the job after sometime,but for surprise it gets executed successfully on next day.
e. As per analysis over all the failed jobs, same things were observed over the different data flows that got stuck during the execution.Logic related to the data flows is perfectly fine.
Observations in the Trace log:
DATAFLOW: Process to execute data flow <DF1> is started.
DATAFLOW: Data flow <DF1> is started.
ABAP: ABAP flow <ZABAPDF> is started.
ABAP: ABAP flow <ZABAPDF> is completed.
Cache statistics determined that data flow <DF1>
uses <0>caches with a total size of <0> bytes. This is less than(or equal to) the virtual memory <1609564160> bytes available for caches.
Statistics is switching the cache type to IN MEMORY.
DATAFLOW: Data flow <DF1> using IN MEMORY Cache.
DATAFLOW: <DF1> is completed successfully.
The highlighted text in the trace log is not appearing in the unsuccessful job but, it appears for the successful one.
Note: The cache type is pageable cache, DS ver is 3.2.
Please suggest.
Regards,
Santosh

Hi Santosh,
just a wild guess.
Would you be able to replicate all the DF\WF , delete original DF\WF, rename replicated objects to original to DF\WF names(for your convenience)   and excute it.
Some time reference does not work.
Hope this should work.

Data Extraction issue from the data source 2LIS_08TRTLP

Hi All,
We are facing one issue in time of extraction from data source 2LIS_08TRTLP(Shipment Delivery Item Data per Stage) in BW. For some out bound delivery no. Gross weight(BRGEW) is coming zero though there is value showing in the source system(ECC) in VL03 and in LIPS table. BRGEW (Gross weight) which is directly mapped in BW infosource. There is no restriction in the extraction and 0 is coming for this field in the first layer extraction.Even in the PSA all values are zero.
We have checked those delivery , delivery is being split into batch . But not the all split delivery is
giving this problem.
With Thanks
Shatadru

Yes I have done the same means I have filled setup table for those shipment no related to that delivery no and checked in the RSA 3 and required value is coming in RSA3 a. That means there is no problem in the Extractor .But I can not pull the data now in BW as it is in Production and every day delta comes .But the in the first layer ODS there is no value for that entry which was previously loaded(Though there is no routine and any restriction).
But I have one observation in the data source that particular field is in INVERSION marked in the Source. But that particular delivery for which it is giving is not canceled or returned or rejected. PGI created for that delivery and delivery status is completed for that.

Viewing and Removing the Time part of the Date field

Hi,
I have Date field in a table.
but in SQL plus when I do
select date from table
this gives me only the Date values and not the timestamps in the date.
I believe Oracle stores 'Date' and 'Time' in fields with Data Type 'Date'.
How do I print the timestamps also in the SQL query?
Moreover, if I have to extract the date field, reset the timestamp to 00:00:00, and store back the date field (with 00 time), how do I do that?
Thanks in advance
- Manu

Hi,
If you want to retry date and time you can:
SELECT TO_CHAR(DATE,'YYYY/MM/DD HH24:MI:SS') FROM TABLE;
If you want truncate time when inserting in a table simply use TRUNC function
INSERT INTO TABLE (DATE) VALUES (TRUNC(YOUR_DATE));
To extract and insert with time 00:00:00
INSERT INTO TABLE1 (SELECT TRUNC(DATE) FROM TABLE2);
I hope this help you.

Parts of the Data went missing when linking two data sets

Hello Everyone!
I have two data sets for my report:
1. an essbase cube which is transformed to a relational star shema transformed by BI Administraion, Im calling the cube with sql (not mdx)
2. a single relational table
In the report Im iterating on the 'product' dimension of the cube and I need to join the cube with the single relational table, because that table holds all the detailed information on each product (mostly text therefore it is not in the cube).
What I did was, joined the two data sets with a Master/Detail link. So far so good. But the thing is, more than half of my data goes missing in the xml-Output when I join those too. If I delete the join, all the data is back again in the xml-ouptut but I cant refer to the details of the relational table.
I tried different things to fix that problem. So I sorted the 1. dataset and joined it again with the 2. dataset. As a result there was still a lot of data missing, but not the same as before.
I find this behaviour really strange and don't have a clue what to do differently.
I would really appreciate some help, because I already spent hours trying to fix that problem.
Thank you!
Edited by: 981323 on 27.02.2013 06:49

Thanks for that. Typically I found this 5 minutes after I posted the request on the forum.
Problem is every time I try and do this the system does not recognise my <?for-each> containing the parameter and says the parameter is not defined. WHen I validate the template it seems to ignore the F completely and complains about to many ends.
I just can't see why it does not work. I am using four records, 2 of each set I am using which link over item number. I can show them seperately but as soon as I add the variable loop ( <?for-each:/INV_GL/GL[GLLITM= $ITM]?> where ITM is my variable and GLITM is that field in the data) it stops working.

How can I extract parts of the EXIF metadata to use in a Smart Collection?

I want to aggregate all of the images I've captured by Capture Month and identify those images that were scanned or have no Capture Date. This question actually attempts to open the door for read access to all of the image metadata and the ability to store some of it in user-identified fields which, somehow, the user will be able to populate.
So - if the date fields (i.e. DateTime Original, DateTime Captured, DateTime Modified ) were broken down into, for example using DateTime Original: Original Year-YYYY, Original Month-MM, Original Day-DD. It may be possible to do this with a redefination of the schema used to define each of the fields. That would be the simpliest, easiest way - if that's possible.
If it isn't possible (or not in the near future, anyway) does anyone have any ideas?
Thanks

With over 45 years in IT (I know, it only means I'm an old man - not that I learned anything ), I observed that many of the problems I identified had simple solutions. The reason they weren't in the original releases was, the testers felt "Why would someone want to do that? Or need that data? Or that field?" Why would you hold an iPhone quite like THAT?
Since Adobe defined the schema that captures the image metadata and defined what fields would be accessable and in what way; the most direct solution to this is to modify the schema through a redefinition of the date fields — all of them — so the individual elements are accessable.
Also, because one of Lightroom's key features is image management, these new data fields should be accessible for Smart Collections. There's at least one other person in this community who's interested in a By Month Across Year sort and I suspect many people don't speak up, even if they have a similar need.
That's what I meant. While outside developers (non-Adobe employees) might be able to come up with a patch for the solution, the underlying problem will still remain until Adobe acts. Solving the problem is the less expensive means of dealing with the issue.
I think.

Separate security for both of two distinct parties - 1 the data owner - 2 the application owner

I have written a web application in .net that runs on a shared server using Sql Server 2012. My program is only useful if I partner with certain data owners. I need to protect my program; they need to protect their data. I am assuming they at least run Sql
Server 2008 R2. I need to interface with their database using a couple of stored procedures. I want these procedures to only be available to my application, and I want the processes and output of the stored procedures to be apparent to me and to my application
alone. I assume they want their data to only be available to my application, not to me generally. This application needs to be available from my website, as well as from their website. I realize this question touches on areas outside of Sql Server Security
as it reaches into basic architecture as well. Any help or pointers to help would be greatly appreciated.
Thank you,

That article discusses the situation in a single instance of SQL Server and is in no way applicable to a scenario where you want to set up trust between a web server and an SQL Server instance.
There is one thing you can do with certificate, that possibly may be appliable to your situation. Say that you develop the stored procedures at your site, and then deploy them at the other site. You want to make sure that the procedures are not modified
locally. To this end yon can sign the stored procedure with a certificate locally. When you ship the procedures, you also ship the public key of the certificate, and in the install script you use ADD SIGNATURE WITH BLOB to sign them. You take that blob from
your home system.
Your web application can then repeatedly check that the procedures are signed with the correct signature. It the procedure is changed locally, the signature is lost. They can re-sign it locally, but not with the certificate you shipped.
This does not prevent other users from calling the stored procedures or look at the code. For that you need trust and contracts between humans.

Toplink resets the time part of the date

Hi,
Using Toplink (DirectToFieldMapping with java.util.Date), while retrieving date information from the DB, the time values are zeroed out (Eg: Fri May 16 00:00:00 IST 2008).
This is happening only when using JDBC thin drivers whereas OCI drivers retrieve the time values properly (Fri May 16 12:30:08 IST 2008).
I tried various versions of ojdbc14.jar and found no difference.
Any help would be appreciated.
Thanks for your time..

HttpServletRequest getReader read part of the post data

Hi all,
HttpServletRequest getReader read part of the post data (even though the conten length is bigger).
It stops after 48k (49,152 bytes)
int sizeOfBuffer = 100;
char[] cbuf = new char[sizeOfBuffer];
StringBuffer inputBuffer = new StringBuffer();
BufferedReader reader = request.getReader();
int chars = 0;
while ((chars = reader.read(cbuf)) >= 0) {
inputBuffer.append(cbuf, 0, chars);
reader.close();
inputBuffer includes parts of the data??
Can anyone help me to know what is wrong??
Thanks,
Lior.

Hi Jakub,
Yes, you can query TDM files for samples with certain specifications. Take a look at this Tutorial Introduction to LabVIEW Data Storage VIs. The section on Query Conditions demonstrates how to look for select samples using the Data Storage express VIs.
I hope this is helpful. Please post if you have further questions!

How does LabVIEW Render the data in 2D Intensity Graphs?

Hello,
I was hoping someone could explain to me how LabVIEW renders it's 2D intensity data. For instance, in the attachment I have included an image that I get from LabVIEW's intensity graph. The array that went into the intensity graph is 90000x896 and the width/height of the image in pixels is 1056x636.
Something I know from zooming in on these images as well as viewing the data in other programs (e.g. Matlab) is that LabVIEW is not simply decimating the data, it is doing something more intelligent. Some of our 90000 lines have great signal to noise, but a lot of them do not. If LabVIEW was simply decimating then our image would be primarily black but instead there are very obvious features we can track.
The reason I am asking is we are trying to do a "Live Acquistion" type program. I know that updating the intensity graph and forcing LabVIEW to choose how to render our data gives us a huge performance hit. We are already doing some processing of the data and if we can be intelligent and help LabVIEW out so that it doesn't have to figure out how to render everything and we still can get the gorgeous images that LabVIEW generates then that would be great!
Any help would be appreciated! Thanks in advance!

Hi Cole,
Thank you for your understanding. I do have a few tips and tricks you may find helpful, though as I mentioned in my previous post - optimization for images or image-like data types (e.g. 2D array of numbers) may best be discussed in the Machine Vision Forum. That forum is monitored by our vision team (this one is not) who may have more input.
Here are some things to try:
Try adjusting the VI's priority (File»VI Properties»Category: Execution»Change Priority to "time critical priority")
Make sure Synchronous Display is diasbled on your indicators (right-click indicator»Advanced»Synchronous Display)
Try some benchmarking to see where the most time is being taken in your code so you can focus on optimizing that (download evaluation of our Desktop Execution Trace Toolkit)
Try putting an array constant into your graph and looping updates on your Front Panel as if you were viewing real-time data. What is the performance of this? Any better?
The first few tips there come from some larger sets of general performance improvement tips that we have online, which are located at the following links:
Tips and Tricks to Speed NI LabVIEW Performance
How Can I Improve Performance in a Front Panel with Many Controls and Indicators?
Beyond that, I'd need to take a look at your code to see if there's anything we can make changes to. Are you able to post your VI here?

Error in the Data Selection - Errors in Source System RSM 340

Hey Everyone,
I'm having an issue with loading a Delta for 0MAT_PLANT_ATTR. This is the second night it has happened, where I get the error "Error in the Data Selection". This error happens in the EXTRACTION part of the Monitor. And, we cannot run another Delta to see if it'll work, we have to delete the old Delta Init, and run a new one. The other error is "Errors in Source System - RSM340". That's as much it gives.
Could anyone suggest why this would be happening? I checked RSA3 in R/3, and no errors on the extraction. I also checked sm37 against the job that loads that data, and it completed successfully. I honestly don't think there's an issue with the data. We cannot have this happen often, and I just need to know if this is something that can be corrected.
Thanks,
John

There is nothing wrong with the TID's or anything like that. There is also no selection criteria in the infopackage.
When the Delta fails, the error occurs under EXTRACTION in the monitor. It seems to be successful under TRANSFER and PROCESSING in the monitor, which I find strange. Also, I run a new Delta Init with Data Transfer, and that works just fine.
So, I'm not sure what it could be?

I would like to open a URL and extract tables from the HTML code of the web

Hi I have opened a URL say www.amazon.com and I would like to extract te tables in that particular web page would somebody out there help me with the code so that the output file displays only the relevant tables containing books and its prices dropping out all other data on the web page . My code for opening the URL goes here. Any quick help would be appreciated
import java.net.*;
import java.io.*;
class ConnectionTest {
public static void main(String[] args) {
try {
URL amazon = new URL("http://www.amazon.com");
URLConnection amazonConnection = amazon.openConnection();
DataInputStream dis = new DataInputStream(amazonConnection.getInputStream());
String inputLine;
while ((inputLine = dis.readLine()) != null) {
System.out.println(inputLine);
dis.close();
} catch (MalformedURLException me) {
System.out.println("MalformedURLException: " + me);
} catch (IOException ioe) {
System.out.println("IOException: " + ioe);
}

The quick and dirty way ( Not perfect and will be prone to errors ) :
As you read the lines using readLine(), look for the string "<table>" (Perhaps using String.indexOf ? -- Java API for class String -- http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html)
If the start tag is found, start dumping lines into a String (string concatenation), keep doing it until you find the end tag, using the method mentioned.
Also, you may want to consider the case where <table> or </table> may not be at the beginning of the line, so you may want to use String.substring to selectively extract part of the line that you want to keep.
Oh, and don't assume that the <table> tag is in lower case, and don't forget that there may be other attributes that are defined in the start and end tags.
I wouldn't recommend using this method other than a quick and dirty extraction. If you really want to do things the right way, use a HTML parser or use the Amazon Web Services as paulcw suggested.
