One of the great characteristics of SQL (Structured Query Language) is the fact that one can develop access and modify data across various tables. There are several benefits to this, including greater ease of manipulation, increased speed of access, and reduced data redundancy. In MySQL (as well as many other SQL languages), this is accomplished via the join command. This tutorial takes a look at several types of the join command including The Cross Join, The Equi-join, The Left Join, and Self-joins.

One of the most powerful aspects of the MySQL server is the amazing amount of control the administrator has over each user's intended behavior. This control can restrict user privileges over a general part of the server, such as limited access to an entire database, but can also be as specific as limiting privileges for a specific table or even column. This article will serve to explain the process in which the MySQL server grants/revokes these user privileges, highlighting in particular the newest additions to the MySQL privilege system, the tables_priv and columns_priv tables. Please keep in mind that the GRANT/REVOKE commands detailed later in this article are only relevant to MySQL version 3.22.11 and up.

This article will aid the reader in learning the basic operations of the MySQL server, including how to make a proper connection, set up the server for consequential manipulation and execute basic commands. The commands covered within this article are among the most important commands within the language, as they form the basis for the more advanced commands.

MySQL Administration correctly administering the MySQL server, including the manipulation the privilege system, and making intelligent decisions about the capabilities (permissions) given to users.
