There are 1.equijoins 2.self joins,3.Crossjoins.
4.Outerjoins->Leftouterjoin,Rightouterjoin,Fullouterjoin.
1.EquiJoins:They are also called innerjoins,In this only
matched rows are displayed to the user.
Example:
select eno,ename,sal,e.deptno,d.deptno,dname,loc from emp e
innerjoin dept d on e.deptno=d.deptno
2.Selfjoin:if the table is joined with table itself.
select distinct (e1.empno),e1.ename,e1.sal from emp e1 join
emp e2 on e1.sal=2* e2.sal(It dispalys emp deatails salary
exactly 2 times with any other emp salary)
