Best Answer

Basically Joins are used to get result from two or more tables and there are two types of joins

inner join and outer join

Inner join : a join of two or more tables which omits the blank rows while checking

Outer join is subcatogorised in to left outer join and right outer join. Which includes blank rows in specifed side if condition satisfies.

Simple outer join is combination of left and right outerjoins.

Apart from these there are

Natural join : cartisian product

Equi join : which includes = operator in condition

NonEqui join : All conditional joins which doesn't uses = in there conditions.
