OUTER JOIN: It is used to retrieve all the rows from one
table but matched rows from another table

LEFT OUTER JOIN: It displays matched row from two tables
and unmatched row from left hand side table

EX: select a.empno,a.ename,a.sal,b.deptno,b.dname,b.loc
from emp a left outer join dept b on(a.deptno=b.b.deptno)

RIGHT OUTER JOIN: It displays matched rows from two tables
and unmatched row from right hand side table

EX: select a.empno,a.ename,a.sal,b.deptno,b.dname,b.loc
from emp a right outer join dept b on(a.deptno=b.b.deptno)
