ERROR_PROCEDURE() returns the name of the stored procedure or trigger where the error occurred. ERROR_LINE() returns the line number inside the routine that caused the error. ERROR_MESSAGE() returns the complete text of the error message. The text includes the values supplied for any substitutable parameters, such as lengths, object names, or times.
