Complex SQL design book [closed]

Question

I know SQL but wanted to master it for use in complex SQL and try to create complex SQL statement in one query. Any book to recommend. I found this book: SQL Design Patterns by Vadim Tropashko. What do you folks suggest?

Answer 1

SQL for Smarties by Joe Celko. I like the way it covers methods for representing datasets that you'd not immediately think would fit into a relational model.
