Answer Posted / jiya jain
The nature of relational database design shows that we will
have related data that is stored in different tables. To
retrieve data from two or more tables we use JOINS.
The JOIN clause tells the database how the data in the two
tables is related so that it can return a correct
representation of the related data.
There are different types of join.
Types of Join are :
1.Self Join
2.Inner Join
3.Outer Join
3.1. Right Outer Join
3.2. Left Outer Join
3.3 Full Outer Join
4.Cross join College Table
