I don't think it is possible to do so what I would but I ask anyway.
I've found that I include the same variables in the top of every Stored Proc I make. These variables are used for logging and error handling. They don't change between stored procs, there meaning if fixed but primary use is to help readability and have a consistent style.
-- Declare code that resolve to possible Error
DECLARE @CONFLICT_CODE AS INT
SET @CONFLICT_CODE= -99
-- Check for Conflict
IF Found > 0
BEGIN
SELECT @Error = @CONFLICT_CODE
END
I would be great to define these in a file that I could include into the stored proc.
