SQL Tutorial

Welcome to the QiSQL Tutorial covering the Structured Query Language or SQL.

You can wander around the tutorial using the menu at the side of the page (or the bottom if you have a fancy mobile gizmo).  The menus are in the order we think you should travel, but please feel free t0 chose your own path.

This tutorial will be based on the free open source database SQLite, because it is free and open source! We like that! Almost everything covered here will apply to other Relational Database Management Systems (RDBMS) like Oracle, MySQL, Postgres etc.  We will try and point out when there are significant differences or potential problems between the various systems.
