Reddit mentions of Sql in a Nutshell (In a Nutshell (O'Reilly))

software developer here. I use sql every day and its an integral part of the majority of the software i work on. That said i would NOT recommend w3schools for sql. w3schools is a great "reference" site for html,css, and sometimes javascript. Meaning it has a lot of information but isn't the best place to learn sql but a good resource once you know it. also w3schools has slowly but surely fallen behind its former glory.

I'd recomend picking up one or more books off amazon. With sql its important to have a database set up to help you learn. if you already do i'd go with: http://www.amazon.com/SQL-Nutshell-OReilly-Kevin-Kline/dp/0596518846/ref=sr_1_16?ie=UTF8&qid=1318654308&sr=8-16. O'reilly makes a large number of computer language related books and its going to take you step by step through learning sql. If you don't have a database set up already and are not sure where to begin then go with: http://www.amazon.com/Language-SQL-Access-Relational-Databases/dp/143545751X/ref=sr_1_12?ie=UTF8&qid=1318654308&sr=8-12. the first chapter(s) are devoted to installing and setting up either Microsoft Sql Server or MySql (and maybe oracle sql developer too) the three most popular database systems used. then its going to walk you threw, step by step, the one you choose.

I'll add im not an actuary so i cant make to many assumptions on what you already know and what you don't but as a software developer find some hands on resources to teach you is definitely what i'd recommend, and there are lots of good and cheep books on amazon to help you do that.

Lastly you may want to post this question on r/programming or r/sql or something like that explaining your situation and they might have even better recommendations.

I have these two books - I think they're great
