Do you know a good source to learn how to design SQL solutions?
Beyond the basic language syntax, I'm looking for something to help me understand:
I started with this book: Relational Database Design Clearly Explained (The Morgan Kaufmann Series in Data Management Systems) (Paperback) by Jan L. Harrington and found it very clear and helpful
and as you get up to speed this one was good too Database Systems: A Practical Approach to Design, Implementation and Management (International Computer Science Series) (Paperback)
I think SQL and database design are different (but complementary) skills.
