Description: 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.
