Answer Posted / soujanya
Nesting of queries, one within another, is termed as a Sub-
Query.
A sub query is executed once for the parent statement
whereas the correlated sub query is executed once for each
row of the parent query.
Example
Select deptno, ename, sal from emp a
where sal = (select max(sal) from emp
where deptno = a.deptno)
order by deptno
