hi
let us suppose we have 5 employees in emp table having sal
2000,3000,2300,4500,3400
subquery- select max(sal) from emp picks only one value i.e
max-4500
there is no limit for IN Operator.see the below example
subquery- select sal from emp where sal/100=0;
if u hav n number of sal's are divisible by 100 the IN
operator must work on all the SAL's divisible by 100.
According to the usage we need to use best query to retrieve
data by keeping min work on server
