A Dud
By pro_crustes
I love most of the O'Reilly pocket guides I have, but not this one. It's badly organized, atrociously indexed, and seems to put a lot of emphasis on things that don't matter, at the expense of things that do. A pocket guide should be able to answer basic questions quickly. This one doesn't. The first chapter dives directly into CASE expressions. That's an odd place to start a book about SQL, but pocket guides aren't meant to be read from one end to the other, so maybe where it "starts" is irrelevant. But that's followed immediately with 25 pages on datatype conversion. Now, throughout all those pages, there is example after example of a pertinent SELECT query. But SELECT itself isn't treated on its own until page 106.
The heart of any pocket guide must be its index. That's where you're going to start when you need to know how "CREATE VIEW" works, what an index is, how to use the LIMIT qualifier, or the proper way to DECLARE a variable or cursor. Well, those things must not be important because they aren't in the index. (The only mention of indexes, by the way, is a bizarre entry reading, "indexes on columns, preventing use of," which isn't really even an accurate description of what appears on the matching page.)
By comparison, the Java Pocket Guide is exemplary. Most of the O'Reilly pocket guides are pretty good. Just not this one.

Excellent Pocket-Sized Reference
By Mostly Mozart
For the past twenty years, I had been generating SQL queries using Access's query-by-example grid. Recently, I found myself needing to write the SQL directly, and this book lived up to its title. It's not an instruction manual. It's a short reference book, and an excellent one.
