This is a very simple but time-saving and powerful tip to build a dynamicSQL query (in SQL Server 7.0) that updates a particular column value present in all tables. And it even works for INSERT.

First, open SQL Server and select SQL Server Query Analyzer from the Tools menu. Type the following SQL statement in the query analyzer window (Type=’U’ specifies user-defined tables):

 SELECT 'UPDATE ',RTRIM(Name),' SET UserID=2 WHERE UserID=1' FROM sysobjectsWHERE Type='U'

Run the SQL statement. Then copy the results from the result window, paste them in the query window, and run them.

You are DONE!
