How to Work With Outer Join in SQL
In this article I am going to explain how to work with outer join.
Introduction
Here I am going to explain what is outer join and why we use outer join. Outer join retrieve data from two or more than two tables same as inner join. Outer join differ from inner join. In outer join, it retrieves all data that satisfy the join condition plus unmatched rows in one or both tables. Outer clause is optional in statement.
There are three types of Outer Join
- Left Outer Join
- Right Outer Join
- Full Outer Join
A Statement that create mcninvoices table
Statements that insert data in mcninvoices table
A Statement that is used to fetch data from mcninvoices table
A Statement that create vendors table
Statements that insert data in vendors table
A Statement that is used to fetch data from vendors table
