If you’re like me and you’re tired of being a SQL hack, producing SQL code that is the product of trial-and-error mixed in with google search results, then you might like to spend $100 on these four (4) volumes. I ordered the whole package on amazon and have it decorating my office shelf. Just about to finish the first book, and while little in it was new, it’s been a good refresher. The tone is light. The chapters are bite size in length. Yet the table of contents shows this series is quite comprehensive. So if you’re just getting started with SQL or feel like it’s time to get that first SQL book you’ve been avoiding, give these a chance.
