The cover of SQL in a Nutshell sports a chameleon, the little lizard well known for its ability to blend in just about anywhere. This is a great choice for the Structured Query Language. SQL has been around since the seventies, helping developers interact with the ubiquitous relational database management system. Thirty some years later, SQL grinds away in the background of just about any interactive web site and nameless other technologies. New alternatives are popping up constantly but I’m going to go out on a limb and say that SQL is going to be around for a long time. Anyone interacting with an RDBMS is in all likelihood going to need to use SQL at some point. For those that do, who also want a handy desktop reference available, SQL in a Nutshell has been there for the last 9 years. The SQL language itself has not stood still over those years, and neither have the products that use SQL, and so now the book has is available in a third edition.
My past as a DBA probably makes me a bit biased, but the reaction I’ve seen the most when a database application isn’t performing as well as would be liked seems to focus on the database side of things. The search for a solution usually seems to center around tuning db parameters, the building (or removal) of indexes and if the budget allows, throwing hardware at the problem. In their new work, Refactoring SQL Applications, Faroult and L’Hermite bring a much wider range of options to the table. There is a lot in this little book for the developer charged with fixing an existing application and I think a lot of good information that could save one from making a number of head-ache inducing mistakes on a new application.
