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.
