elegant = simple, concise, easy to understand.
Looks elegant to me.

Subject: SQL question
Hello Listers,
How to find out the COUNT of DISTINCT values of multiple columns?
For eg.
SQL> SELECT DISTINCT ename FROM emp;
-- This works.
SQL> SELECT COUNT(DISTINCT ename) FROM emp;
-- So does this.
SQL> SELECT DISTINCT ename, job FROM emp;
-- And this too.
SQL> SELECT COUNT(DISTINCT ename, job) FROM emp;
-- So why does this fail?
I can do a COUNT(DISTINCT ename || job), but that doesn't seem to be
elegant
way of doing it.
I have a feeling I might be missing some fairly basic syntax, but feeling
dumb is better than suspense.
Thanks & regards,
Charu.
