Need online help for SQLServer stored procedures.

Where can I find a good online manual and/or tutorial for writing stored procedures with SQL Server? The online help kinda sucks.

Thanks,
Alvaro

There's an online textbook at the bottom of this page and stored procedures is one of its chapters.

Thanks! That's exactly what I needed.
