Is it possible for a trigger to find the name of the stored procedure that modified data?

Question

There are a few stored procedures that routinely get called by a few different systems to do maintenance on a few tables in our database. Some are automated, some aren\'t.

Answer 1

you can try: CONTEXT_INFO

here is a CONTEXT_INFO usage example:

in every procedure doing the insert/delete/update that you want to track, add this:

DECLARE @string        varchar(128)
       ,@CONTEXT_INFO  varbinary(128)
SET @string=ISNULL(OBJECT_NAME(@@PROCID),'none')
SET @CONTEXT_INFO =cast('Procedure='+@string+REPLICATE(' ',128) as varbinary(128))
SET CONTEXT_INFO @CONTEXT_INFO

--do insert/delete/update that will fire the trigger

SET CONTEXT_INFO 0x0 --clears out the CONTEXT_INFO value

here is the portion of the trigger to retrieve the value:

DECLARE @string         varchar(128)
       ,@sCONTEXT_INFO  varchar(128)
SELECT @sCONTEXT_INFO=CAST(CONTEXT_INFO() AS VARCHAR) FROM master.dbo.SYSPROCESSES WHERE SPID=@@SPID

IF LEFT(@sCONTEXT_INFO,9)='Procedure'
BEGIN
    SET @string=RIGHT(RTRIM(@sCONTEXT_INFO),LEN(RTRIM(@sCONTEXT_INFO))-10)
END
ELSE
BEGIN --optional failure code
    RAISERROR('string was not specified',16,1)
    ROLLBACK TRAN
    RETURN
END

..use the @string
