The previous few pages covered some slightly more advanced SQL than the last tutorial. However, it still covers only the most basic portions of SQL. I may write more tutorials in the future that go into greater detail. However, the real point of this series of tutorials is to learn C#, not MS-SQL. If you're interested in more information, please see what Google or your local community college may have to offer. You will easily learn this and much more in a single SQL class.

For our purposes, we now know how to create, insert, update and delete data in tables. We've also touched on proper db structure, though really the best way to figure this out is to do it so it makes sense. Once you've built a poor database structure or two (or worked with someone else's poorly-implemented database) you'll get an appreciation of the importance of building your db in a scalable, manageable way. As with C#, only practice will make you truly adept.

This tutorial ends the current section on SQL. Next we'll dive back into some C#.
