what is the diffrence between inner and outer join

Answer Posted / saifur rahaman

difference between inner join and outer join is:

inner join means it selects same data only in both the
tables
outer join means first it selects same data and second it
selects different data from the both tables.

Outer Join:

There are three types of outer joins namely:
>>Left Outer Join---For retreiving all the columns from the
first table irrespective of the column match.
>>Right Outer Join---For retreiving all the columns from
the second table irrespective of the column match
>>Full Outer Join---For retreiving all the columns from
both the tables irrespective of column match.
