• How to case statement based on the array of values of 3 or more?

  I'm trying to figure out how to do a comparison or case structure... based on the creation of an array of boolean 3 (or maybe more).

  I have a table (it's from a serial connection, and I am conversion back to a table to work with) [t, F, F] in this case I would like to display on a status indicator "STBY".

  If the array is defined on [F, T, F] I want to display in this indicator "ON".

  If the array is defined on [F, F, T] I want to display in this "EMPTY" indicator

  I can not understand how to compare combinations of things... I read in an array of bytes, and the first 3 bits in this example, determine what to display in a status... I can't figure out how to do with structure case... or without some channels to research and/or bad comparison...

  Any suggestions?

  Thanks in advance,

  Cayenne

  You can use search 1 d array and find the first real.

  Or you could convert the table of Boolean integer U8 and integer that results to determine which cases to run.  (4, vs, vs 1-2)

• Why this CASE statement would not work?

  If I use a CASE in my SELECT statement and met a strange thing and just need help to understand why he did it.
  
  When I type this, it does not work:
  
  CASE TRIM (Column1)
  WHEN NULL THEN Column2
  WHEN 'foo' THEN Column2
  Of ANOTHER Column1
  END AS NewColName
  
  I use this query in an Oracle procedure to insert data into another table. The data inserted in the column of NewColName end up being 4 empty spaces, located in Column1. In the logic of this, TRIM must remove all the empty spaces, and he should get mapped to the first statement WHEN, who must insert the value of Column2, but that does not occur. I tried the following versions of the first line as well:
  
  LTRIM (RTRIM (Column1)) CASE
  CASE of REPLACE (Column1, ' ', ")
  
  and they all produce the same result. I also tried to change WHEN NULL for WHEN " and it changed nothing. However, when I rewrite the statement in this way it works the way it should:
  
  CASE
  WHEN TRIM (Column1) IS NULL, Column2
  WHEN TRIM (Column1) = 'foo' THEN Column2
  Of ANOTHER Column1
  END AS NewColName
  
  In my mind, it seems that these two methods are trying the same thing, why we could work and the other not? Only, it has no sense to me.
  
  Thank you

  Hello

  Welcome to the forum.

  In your first statement, you have

  WHEN NULL THEN.

  This is the same as x = NULL.

  Nothing is never equal to NULL, if you find yourself in your ELSE clause.

• Nested Case statement

  Hello
  I need help implementation of multiple Case statements in a select statement. I can not it works in a statement.
  SELECT statement

  select distinct 
  allt.fk_jobcode_id as Job_Code,

  HAVING (count(fk_jobcode_descr ) = 1)
  order by Classification asc, Department_Division asc

  1st CASE statement combines the Department_Name and Division_Name values, but does not display the Division_Name if the value is "N/a".

       dept.department_name|| ''||nvl2((CASE WHEN div.division_name <> 'N/A'

  I need to extend this now using this CASE statement, which displays the text "Public works" If the department_id = 00072.

       (CASE dept.department_id 
       When '00072' then 'Public Works'
       Else dept.Department_Name
       End) as Department_Name,

  but once I change the select statement I get only value "Public works" for the Department_Division value. Does not meet Division_Name data. Does anyone know how to combine these CASE statements? Thanks for reading this thread also.

  Hello

  I think you want something like this:

  SELECT       ...
  ,       CASE
             WHEN  department_id = '00072'
             THEN  'Public Works'
             ELSE  dept.department_name
         END
         ||
         CASE
             WHEN  div.division_name != 'N/A'
             THEN  '/' || div.division_name
         END          AS department_name1
  ...
  

  Whenever you have a problem, post a small example (CREATE TABLE and only relevant columns, INSERT statements) of all database tables.
  Also post the results you want from this data, as well as an explanation of how you get these results from these data, with specific examples.
  Always tell what version of Oracle you are using.

  The initial error was just a problem with your procedure. The other has to do with how you use the CASE statement.
  The code seems a bit long for what you're trying to do. Could you describe what your needs are?

• CASE STATEMENT DOES NOT HIERARCHY

  Hi Experts

  I have this case statement:

  BOX WHEN ' @{pvCalType} "="Cal1"THEN"Calendar Cal1"". "" Year. "

  WHEN ' @{pvCalType} "="Cal2"THEN"Calendar Cal2"". "" Year

  ANOTHER NULL

  END

  All the columns in the YEAR of different sizes have properties of the hierarchy.

  When I view my results of this statement, there is no hierarchy.

  I want the hierarchy in order to drill down of the YEAR > QUARTER > MONTHS

  Help, please.

  Hello

  do you have other possible values for "pvCalType"?

  If not try this formula: "@{pvCalType} schedule". " Year. "

  (not sure this is the right syntax, if it does not work after the return of the error and I get the right thing...)

• Case statement in the SQL Query prompt dashboard

  Hi Experts,

  I use the following case statement to generate default values in the prompt dashboard based on a condition (the other guest-generated values). Below are two of the query I've tried and the syntax error. I tried all the possibilities (like giving apostrophes, double quotes, don't quote not etc.), but could not understand the question. Don't know what exactly I'm missing here.

  Query 1:

  SELECT

  CASE

  WHEN @{PRType} = monthly THEN 'Participant pay '. "" Amount of PayRate "="15000"

  WHEN @{PRType} = daily THEN 'Participant pay '. "" Amount of PayRate "="650"

  WHEN @{PRType} = hourly THEN 'Participant pay '. "" Amount of PayRate "="1"

  ELSE ' 0'

  END

  OF 'PA-Participant pay. '

  Query 2:

  SELECT

  CASE

  WHEN @{PRType} = monthly THEN "15000"

  WHEN @{PRType} = daily THEN "650"

  @{PRType} = schedule THEN '1'

  ELSE ' 0'

  END

  OF 'PA-Participant pay. '

  This is the query that is generated in the log with error message file.

  1 log message:

  
  

  SELECT CASE WHEN Hourly = Monthly THEN "Participant Payroll"."Payrate Amount" = '15000' WHEN Hourly = Daily THEN "Participant Payroll"."Payrate Amount" = '650' WHEN Hourly = Hourly THEN "Participant Payroll"."Payrate Amount" = '1' ELSE '0' END FROM "PA-Participant Payroll"

  Comment 2:

  Sorry, I wasn't clear... you must always put this CASE statement in a valid SQL SELECT statement.

  SELECT

  CASE

  When ' @{PRType}' = 'Monthly' THEN '15000'

  When ' @{PRType}' = 'Daily' THEN '650'

  ELSE '0' END

  OF 'PA-Participant pay. '

• A CASE statement in summary

  Hi all!

  A work colleague published some analysis I built and messed up some column formulas, I did.  I am trying to summarize this case statement:

  CASES WHERE "claim Cmplt - various. "" Number special String ' AS ' % ~ 109 ~ %' THEN 'D1BC' WHEN ' claim Cmplt - various. "" Number special String ' IS NULL OR "claim Cmplt - various. "" String of the special issue "LOVE NOT ' % ~ 100 ~ %" OR "claim Cmplt - various" "." " Chain of the special issue"do NOT LIKE ' % ~ 99 ~ %" OR "claim Cmplt - various" "." " Chain of the special issue"do NOT LIKE ' % ~ 49 ~ %' THEN 'VSC' END

  The formula works like this.  When I go to SUM it, I'm missing something... you can identify what it is?

  SUM (CASE WHERE "claim Cmplt - various".) "" Number special String ' AS ' % ~ 109 ~ %' THEN 'D1BC' WHEN ' claim Cmplt - various "". "" "Number special String ' IS NULL OR" claim Cmplt - various. "" String of the special issue "LOVE NOT ' % ~ 100 ~ %" OR "claim Cmplt - various" "." " Chain of the special issue"do NOT LIKE ' % ~ 99 ~ %" OR "claim Cmplt - various" "." " (Chain of the special issue"do NOT LIKE ' % ~ 49 ~ %' THEN 'VSC' END)

  Thanks gurus!

  Don't know what you expect here by using sum. Money is not the columns of type char, but you can go for the County that would work.

  hope you guessed it.

• How to track down where a specific enum is used in a switch case statement?

  Hi all

  I have an application of simulation of machine quite complex state that I add a 'mode' feature for. Some States in the application, rather than the blocks by default of running code, a VI a VI class for each mode will be instead (for example for modes A and B, initialization status has now Initialization_modeA and Inilitalization_modeB). This results in many cases structures everywhere, and I can't figure out how to ensure that, when adding a new mode, I have add the case of this mode of each switch case. Is it as simple as having a default case with a pop-up box? Or is it possible OOP I can handle this?

  Go right on what you told us, you could have each mode inherited from a common ancestor that defines a set of common States (or methods in this case). Whenever you want to add a new method, you can create a new class and override simply each method with this specific class has to do. Instead of having a State of init for each mode, you only then a common State of init, which would then distribute the code correct init based on what class you are using.

• How to fill a table only if a case statement runs?

  Hello. I want to have a while loop with a case statement. When the case is true, it should read the analog data each iteration of the while loop via Daqmx and store these values in a table. If the case is wrong, I don't want to read all the data or to store anything else in the table. When the loop is finished, I want to have this available table to write to a file or something. How can I go about it?

  Search for a "shift register. This will hold your data. In the case of fake feed the data in the table back through without change. In the case of true add the new value in the table to "build the table" or even better "subset of the table to replace' for a defined table size.

• How can you change a menu drop-down menu in a case statement?

  Hello

  I'm trying a table find vi. This VI will be an existing xml file and once the user has selected access to its equipment, input, output and frequency it put all of these options in a string and search the XML for this exact table name and post it on one screen of output. The problem I have is my entry and exit selection must be a little different depending on the chosen equipment. I thought I could use an instruction box to change the options of selectable input and output, but I ran into snags a lot with it. For whenever I have to put a new drop of entry and exit in the drop-down menu in the case statement, he wants to put a new one in the front (I only want to enter and exit not only three I have two inputs and outputs hidden right now). I think I'm using the wrong case statement... Can someone help change my input and output, selectable options depending on the chosen equipment. Attached is my xml file, Array Find.vi (the original) and table Find_Test.vi (that's what I'm trying to change).

  Thank you

  dlovell

  Hi dlovell,

  A few changes in the attached VI:

  Requirements/possible Solutions

  • When the value of the equipment, do something
  • • Add the cases to the value of equipment change event
  • Do something = decide what channels to write, to change the input and output strings
  • • Read material value changed
    • Decision (case structure)
    • Channel (same method as the previous mod)
