SQL*Plus column separator - sql

Question

I'm in scott user in SQL*Plus and is it possible in this select to separate columns by tabulation instead of the default space?
SELECT empno, ename, job FROM emp
Unfortunately this doesn't work:
SELECT empno '\t', ename '\t', job '\t' FROM emp
Instead of:
EMPNO ENAME JOB
7369 SMITH CLERK
7499 ALLEN SALESMAN
7521 WARD SALESMAN
7566 JONES MANAGER
7654 MARTIN SALESMAN
7698 BLAKE MANAGER
7782 CLARK MANAGER
7839 KING PRESIDENT
7844 TURNER SALESMAN
7900 JAMES CLERK
7902 FORD ANALYST
7934 MILLER CLERK
I want more space between columns:
EMPNO ENAME JOB
---------- ---------- ---------

7654 MARTIN SALESMAN

Answer 1

Use the COLUMN command (see SQL*Plus® User's Guide and Reference) and format your report according your wish

Answer 2

An easier solution would be:
set colsep ' '

Answer 3

As sqlab already pointed out you need the COLUMN formatting options which are in SQL*PLUS.
Since the docs aren't very readable, here is what you need:
COLUMN EMPNO FORMAT A10
COLUMN ENAME FORMAT A16
COLUMN JOB FORMAT A9
If you need to do it in regular SQL you can use this:
SELECT rpad(empno, ' ', 11) empno
, rpad(ename, ' ', 17) ename
, job
FROM emp
