Title: One of the all-time worst technical books I've encountered
Product review: Someone asked me how to perform a SQL Union a few minutes ago. I looked up on my bookshelf and saw "SQL Programmer's Reference". My first thought was "why do I still have that piece of garbage?". My second thought was, "well I should be able to find my answer in there, and THEN I'll throw it away". Here's what I found:UNION Returns all rows selected by either queryThat was all it had to say - no syntax, no examples, no nothing. Needless to say, completely accurate and utterly useless.To me it's perplexing that this small SQL reference book is ambitious enough to attempt to cover Oracle, Informix, AND Sybase extensions but can't even provide decent coverage of essential SQL syntax.Here's a useful query:DELETE SQLProgrammersReference from Bookshelf
