Well you'll get a lot of places on the web where you can get sql tutorials, just go through any of the sites and read them online> I would recommend w3school for learning MySQL basics, its good .

And If you wanna learn SQLi then you must learn MySQL and not SQL Server 2003, 2005 or maybe 2008, since cracking MySQL sites is easier than, SQL server sites, as they have a lil more security, but ican be done, So once you are done with MySQL vulnearable sites you can get on with other things very easily also you need Googe Dorks to get on with SQLionce you are on okay with how to use these dorks you'll be able to make your own dorks perfetly, and will be able to deface many other sites..

Hope this helped, These are some links for the Google dorks:--
