I just wanted to post a few good resources that have helped me out a lot:
http://www.sqlcourse.com - A great place to learn about SQL queries (TSQL) . Each lesson will teach you a little bit about setting up queries and allows you to submit a query of your own with an actual SQL db.
http://www.sqlcourse2.com - Once you have completed the first course you can continue to part 2 with more advanced SQL topics.
http://msdn2.microsoft.com/en-us/library/ms678086.aspx - MSDN ADO API Reference - The common link between VBA and SQL is ADO, and where better to learn, than from the people that developed it. This is the most complete reference on ADO around with working examples and in-depth explanations of all the Members and Objects of the library.
I hope these resources can help someone else. I am really excited about this new addition to the forums and hope to learn a lot!
Thanks,
Chad
