TSQL Basics: SQL Server Join Types

Intended Audience

Database programmers and new administrators who are familiar with TRANSACT SQL, may know simple joins, who would like to know more about OUTER JOINS, LEFT JOINS, RIGHT JOINS, CROSS JOINS, and SELF JOINS.

Abstract

What is the difference, and how can you use joins correctly. Sometimes an inner join is the right join type to use, other times the left outer join, right outer join, full outer join, cross join or self join. In this session you will first gain an understanding of the differences between each of these types of joins, and when they should be used. Then we’ll explore some common uses for joins, such as replacing a not in clause with join to get the same results with better performance. You will take home the right foundations to get at the data that you want.
