SQooLer is an SQL plugin for the Eclipse platform.

You can create and run SQL statements like SELECT, INSERT etc., or PL/SQL scripts. Your results appear in a separate view (SELECT's in table, PL/SQL in info field). All files with *.sql extension are opened in a syntax-highlighted editor.

It is a useful tool for developers who are writing J2EE applications. You don't have to open an other tool to check your database, just switch the perspective (or even not :-) ) and run your control script!
