There seems to be many different extensions/types of "SQL".
I'm looking to learn SQL for Database Administration.
What programs does someone who does SQL Database Admin work use on the daily basis?
(I have Microsoft Excel, Access and Visual Studio 200

Do you have any Books/Online Videos/Courses you might recommend me picking up?
Also is their any type of Certification tracks for SQL, I'm currently looking into a .NET/C# track and was wondering if SQL has a track.
Also what is the difference between MySQL and SQL? MySQL seems to be from Sun and more Web-Based...
Hopefully you guys can get these questions answers for me
