Hi there, can someone tell me what the differences between SQLServer and MySQL are.

I'm presuming MySQL is just a cut down version of SQLServer (oh and its free !) but what are the actual differences. What can i do in SQL that i can't do in MySQL.

I have a project to research and work are too tight to give me a copy of SQL to take home with me (although it will be SQL that i will do the work on eventually).

Any help would be greatly appreciated.

Cheers
