Learning SQL can be very rewarding. Once you have a basic understanding of SQL, you can start to develop more advanced websites, and you can (hopefully) charge more money for doing so!
This free SQL tutorial covers the SQL (Structure Query Language) syntax and its various SQL commands. It assumes a basic knowledge of databases and database design.
Although not essential, you will benefit most from practicing the examples on your own computer - this would require a database program such as MySQL, SQL Server, or Oracle to be configured on your machine.
If you don't have a database program installed on your machine, don't despair, you will still learn what SQL is and its syntax. Then, when you do find yourself a database system, you will know just what to do!
If you don't have a basic understanding of databases, start with the database tutorial, which steps through the fundamental concepts of databases. Once you've completed that tutorial, come back and breeze through this one!
