http://sqlfiddle.com/#!4/47961/13

But it is not working .

Where am i wrong?

Answer 1

Select salary from emp where salary < (SELECT MAX(SALARY) FROM EMP ));

you can apply having clause where you used group by , here there is no group by than just use where

The HAVING Clause

The HAVING clause was added to SQL because the WHERE keyword could not be used with aggregate functions.
