RE: SQL question

Think you need a distinct in there, yes?

select distinct least(a, b) a, greatest(a, b) b from my_table
where least(a, b) <= greatest(a, b);

Otherwise you get dupes, which he didn't have in his sample output.

select least(a, b) a,

           greatest(a, b) b

from my_table

where least(a, b) <= greatest(a, b)

Assuming of course that the table isn't in the multi-million range.

Hi,
I have the following table below

SQL> select * FRom mytable;
A B
---------- ----------

1 2
3 4
2 1
5 6
4 3

5 rows selected.

and I like to get the following output:

A B
---------- ----------

1 2
3 4
5 6

basically (1,2) is the same as (2,1) and I would just like to display any of
those combination just once.

Not sure how I can write a SQL to extract the data. Can someone help.

TIA. Geraldine
