Question

I have a stored procedure in SQL Server 2008 that needs to delete a few rows of data. But when I run it, it returns a fail and a value of -6.

ALTER procedure [dbo].[p_CaseFiles_Exhibits_DeleteExhibits]
  @ExhibitID int
, @Message nvarchar(50) output
as
declare @FileID int
set @FileID = (select FileID from CaseFileExhibits where ExhibitID = @ExhibitID)
begin transaction
  begin try
    delete from CaseFileExhibitMovementTracking where ExhibitID = @ExhibitID
    delete from CaseFileExhibitAttachments where CaseFileExhibitID = @ExhibitID
    delete from CaseFileExhibits where ExhibitID = @ExhibitID
    delete from CaseFileExhibitPropertyLink where ExhibitID = @ExhibitID
    update CaseFileQuickStats set ExhibitCount = ExhibitCount -1 where CaseFileID = @FileID    
    commit transaction
  end try
  begin catch
    set @Message='Fail'
    rollback transaction
  end catch

I can’t seem to find what’s wrong.

You’re able to check out the messages yourself, add this to your CATCH block:

SELECT
ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;

You may want to change that SELECT to PRINT, and then you’ll be able to see the results in the ‘Messages’ tab when running the SP within SSMS.

I suspect it’s a problem with a Foreign Key or a possible trigger.
