A query is nothing but if we want to evaluate one thing we
will write query. like
select * from emp; --->> query
A Query is evaluated once for each and every row from the
parent statement is called corellated Query.
like
select * from emp outer where sal= ( select avg(sal) from
emp e where dept.e=dept.outer) --> corelated query
