• SQL query using the MAX function

  I am trying to display only those records where the "date_entered" is the most recent by case number.

• SQL using the analytic function

  
  Hi all

  I want a help in the creation of my SQL query to retrieve the data described below:

  I have a test of sample table containing data as below:

  State ID Desc

  MICHAEL 1 T1

  ACTIVE 2 T2

  T3 3 SUCCESS

  DISABLE THE T4 4

  The thing I want to do is to select all the lines with an ACTIVE status in the table but is there is no ACTIVE status, my request will give me the last line with MICHAEL status.

  I can do this in a single request by using the analytical function for example, if yes can yiu help me on the request of unpacking.

  Kind regards

  Raluce

  Something like that?

  I had to fix it.

  with testdata until)
  Select 1 id, "T1" dsc "DISABLED" status of Union double all the
  Select 2 id, 'T2' dsc, the status "ACTIVE" of all the double union
  Select id 3, "T3" dsc, the status of 'SUCCESS' of all the double union
  Select 4 id, "T4" dsc "DISABLED" status of double
  )

  Select
  ID
  dsc
  status
  of testdata
  where
  status =
  -case when (select count (*) in testdata where status = 'ACTIVE') > 0
  then 'ACTIVE '.
  Another 'DISABLED '.
  end
  and)
  ID in (select id from testdata where status = ' ACTIVE')
  or
  ID = (select max (id) in testdata when status = 'DISABLED')
  )

  STATE ID DSC

  '2' 'T2' 'ACTIVE '.

  Maybe it's more efficient

  Select
  ID
  dsc
  status
  of testdata
  where
  status =
  -case when (select count (*) in testdata where status = 'ACTIVE') > 0
  then 'ACTIVE '.
  Another 'DISABLED '.
  end
  and
  ID =)
  -case when (select count (*) in testdata where status = 'ACTIVE') > 0
  then id
  on the other
  (select max (id) in testdata when status = 'DISABLED')
  end
  )

• How to use the TRUNC function with dates in the expression builder in OBIEE.

  Hello
  How to use the TRUNC function with dates in the expression builder in OBIEE.
  TRUNC (SYSDATE, 'MM') returns 1 July 2010"where sysdate is July 15, 2010 ' in SQL. I need to use the same in the expression builder in the logical layer mdb column.
  
  
  Thanks in advance

  Use it instead:
  TIMESTAMPADD (SQL_TSI_DAY, (DAYOFMONTH (CURRENT_DATE) *-1) + 1, CURRENT_DATE)

• Do I need to use the NVL function for this request?

  I seem to have some problems using the NVL function on a date. I'm trying to create a query pulls back just a date a file was sent between the sysdate and the date_sent more a minute. Here is the code I use...
  
  Oracle: 10.2 G
  

  SELECT date_sent as date_sent
  INTO    iDateSent
  FROM    tableX
  WHERE  file_id= 9999
  AND    date_sent BETWEEN sysdate AND date_sent + 1/1440; 

  Currently Output (null):

  DATE_SENT

  Desired output when date_sent is null:

  DATE_SENT
  0:0:000 0:00:00

  Note:
  date_sent column is in a normal date - same format as sysdate format.
  
  The problem I encounter is when date_sent is null, the stored procedure, I built crashes because date_sent returns a null and a null value cannot be stored in the variable 'iDateSent '. I was thinking about using the NVL function here to resolve, however, I'm not entirely sure who will work with the above query. Any thoughts?

  Hello

  you said: "desired output when date_sent is null: date_sent: 0".
  It is not possible to have a date of 'zero '.

  "and a null value cannot be stored in the variable 'iDateSent'. '.

  I do not think: If this variable is declared normally (without any not null not constrained to this topic) so that it can contain a null value. (it's 99% of the time in PL/SQL).

  I think it's that your SQL retrieves no rows, to manage what you should put an exception handler:

  begin
  SELECT date_sent as date_sent
  INTO    iDateSent
  FROM    tableX
  WHERE  file_id= 9999
  AND    date_sent BETWEEN sysdate AND date_sent + 1/1440;
  exception when NO_DATA_FOUND then
   iDateSent:=null;
  end;
  

  So what you can do if you don't want the date empty a nvl:

  return(nvl(iDateSent,sysdate));  -- or another date ...

• How doi send texts using the speech function without hitting the Send button?

  using the speech function in texting, how to send the text without actually pushing the Send button? When I say 'send' or 'send message' he just keeps typing

  "Hey, Siri, send a message to Bob. Siri will then ask you what you want text Bob. Once you stop dictating, Siri will ask then if you're ready to send the message. Say, "Yes." It's really very nice.

  If you are already in the message app and using speech-to-text, you must press the Send button.

• Cannot use the Val function in a script use

  I'm trying to convert a text string (binary number) in a number by using the Val function in a script of use but the colors of tiara the term Val in red and the script produces an error indicating "Variable is undefined:"Val"

  Why is that happen? Some functions are not allowed in use scripts?

  In addition, it seems impossible to use debugging in my use - if I try to add a variable to the Watch window, there never have any value even if I put a breakpoint on this line of code. Would it not possible to debug scripts use?

  David,

  regarding your question on "Val" I would like to direct you to the "File.Formatter.ParseString" function which is part of the API available at DataPlugins.

  CDbl and CLng do a good job in general, but they are dependent on the local configuration of the PC. 'ParseString' is so much more reliable.

• When I use the library function node call in real time, is loaded only once for all or load the DLL whenever it is called?

  When I use the library function node call in real time, is loaded only once for all or load the DLL every time when it is called?

  I have a critical application in real time, in which I use a piece of DLL function developed in C++.  It is ok?  Make sure any senior developer?

  Thank you in advance.

  The user interface thread is the thread that is used to update the user interface. It's slow. And it's supposed to be that way because humans are slow.

  The call library function node can be configured as this thread to use in the configuration for it dialog box. Please visit the LabVIEW documentation on how to do this.

• How can I use the BCGTransform function to treat the 16-bit Image?

  Hi ~

  I use LabWindowsCVI8.5 and NI Vision to make the treatment of the Image. When I read the "IMAQ Vision for LabWindowsCVI Reference Manual", I found that the imaqBCGTransform function only supports 8-bit Image, while I do the BCG to turn on 16-bit image. Are there solutions to use the BCGTransform function to deal with the 16-bit Image? Or any other feature that could make the correction Gamma, contrast and brightness on the 16-bit Image?

  Thank you very much!

  because imaqBCGTransform is implemented as a lookup table, we can understand why it is limited to 8-bit images.

  Now let's take a look at the definition of each of this mandate (from the NI Vision Concepts documentation):

  -brightness: a constant added to the components red, green, and blue pixel of color over color, decoding of the process;

  -contrast: a constant multiplication factor applied to the components of the luma and chroma of a pixel of color in color to decoding process.

  -gamma correction: expand high gray-level information in an image while removing information of low level of gray.  (the chapter on lookup tables gives some examples of corrections gamma)

  now that you understand that this transformation is a simple mathematical function, simply calculate the correction for each pixel on your 16-bit images.

  I know not the exact formula used by the imaqBCGTransform function, but you should be able to approach by performing some tests on images 8 bits with the original function... or you can make your own formula... or find one on the net... or you can ask someone at home OR you give the formula...

• Does anyone have an example VI for using the SendInput function in User32.dll?

  I would use rather MouseEvent.  I looked at my VI and it can be cleaned up a bit, but it works for what you want to do.

  5. on the Paint toolbar, click on edit and then click on paste. The image will now be pasted in a Paint window. You may need to accept a dialog resize if the image is larger than the current document.

  6. now, from the toolbar to the left of your screen, click on the Selection (the oblong dotted box) tool. With the selection tool, select the entire surface of the table you want to copy. Once selected, click on modifier change again, then select Copy.

  7. now, open Microsoft Word.

  8. then place the cursor where you want the table to set, and then press the CTRL and V together on your keyboard.

  9. the image of the table should now be pasted into your Word document.

  Alternatively, you can use the cutting tool (click on the Start button and type snipping tool in the search field). Select the table you want in the pdf page using the cutting tool and then open word and paste the table in word.
