SQL 2005 Express

This application is a good replacement for SQL Query Analyzer... try it, if you just have installed VS2005 Beta 1, you will need it.

QA Replacement Application
Due to the lack of GUI tools distributed with the first releases of SQL Server 2005 Express (download) the QA Replacement Application was created. This application does not have all the functionality of Query Analyzer but as time goes on it gets closer. QA Replacement allows the user to run scripts, create DDL from dragging objects to the editor, see the event profiler for executing T-SQL and viewing the Show Plan for query executions.

...and here you can get some samples.
