>Dear Mike,

>Thank you for your help .... According your seggestion, it's work but the ASP page will stop at the error statement and show the error message on the page immediately. I can't control the error by myself. I would like to show prompted message to user when the error occurred during stored procedure processing has error. It is because the updating ASP page is a hidden page on the screen. The user didn't see any error message on it if error occurr during the process. Thanks a lot!!

SQL Server 200 Stored Procedure Programming; Dejan Sunderic and Tom Woodhead; Osborne; suggested by SQLSister. A good solid reference on stored procedures. I like the sections on error handling; triggers; and dynamic SQL.
