Hi,
I want to display the department no. and the no. of employee in each department from EMP Table.(in a Single Row). Pls help me how to write the query for that.
I had one query which display the result in 3 rows.

select deptno, count(*) from emp
group by deptno;

Dptno Count(*)
10 5
20 3
30 4

I want to display this 3 rows in a single-row.
For Eg:

Dpt10 Count(*) Dpt20 Count(*) Dpt30 Count(*)
10 5 20 3 30 4

The output in this forum is not proper but try to understand that the no. 5,3 & 4 should be below count(*) column and 10,20 & 30 should be below deptno.

select '10 '||sum(a)||' 20 '||sum(b)||' 30 '||sum(c) "Dept vs count(*)" from(select decode(deptno,10,count(Sal)) a, decode(deptno,20,count(Sal)) b, decode(deptno,30,count(Sal)) c from emp group by deptno)
