Answer / apoorv sharma
You use INNER JOIN to return all rows from both tables where
there is a match. ie. in the resulting table all the rows
and colums will have values.
In OUTER JOIN the resulting table may have empty colums.
Outer join may be either LEFT or RIGHT
LEFT OUTER JOIN returns all the rows from the first table,
even if there are no matches in the second table.
RIGHT OUTER JOIN returns all the rows from the second table,
even if there are no matches in the first table.

Answer / 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.
