SQL Server stored procedure parameter output

Question

I have a stored procedure that I have scaled down considerably for the purpose of this question but in essence the issue I need assistance with is this.

If a row in tab

Answer 1

See the changes:

 -- this does not work for multiple IDs
  SELECT @IPV_ID_Found = @IPV_ID_Found + ',' + (CAST(@IPV_ID AS VARCHAR(500))) 

then you will get a concatenated list of values, like 1,2,3,4,5

BUT if you need to return a recordset, then you need not OUTPUT parameter, use the table variable instead:

declare @IPV_ID_Found table(Item varchar(500))

IF (@IPV_Status ='closed')
BEGIN
UPDATE TEST_TBL
 SET
    Status  = 'xyz',        
 WHERE                  
    ID      =  @IPV_ID 

  -- this works for one ID
  insert @IPV_ID_Found 
  VALUES (CAST(@IPV_ID AS VARCHAR(500)))    

  -- this does not work for multiple IDs
  INSERT @IPV_ID_Found 
  VALUES (CAST(@IPV_ID AS VARCHAR(500)))

  SELECT Item FROM @IPV_ID_Found                  
END
