This is an excellent book on SQL. It begins with the basic syntax of SQL statements such as SELECT, INSERT, UPDATE, and DELETE and then covers more intermediate concepts such as joining, string manipulation, and date/time arithmetic. The most rewarding section was the two chapters on embedded and dynamic SQL. It's hard enough to find a good SQL book that covers embedded SQL at all, and this one explains it so well...from declaring cursors to allocating descriptors to fetching rows. This is a well-rounded, well-written text.
