SQL & PL/SQL

Hi All,

I have the following query and its give a desired output like a matrix.

SELECT  DEPTNO,
 DECODE(DEPTNO,10,COUNT(*))TEN,
 DECODE(DEPTNO,20,COUNT(*))TWO,
 DECODE(DEPTNO,30,COUNT(*))THREE,
 DECODE(DEPTNO,40,COUNT(*))FOUR
FROM EMP
GROUP BY DEPTNO

I want to have a output like the below format, can the pro's help me with the right query or give a approach for the same.

Deptno    10         20       30      40
Values    100       200     300     400

Thanks in advance
