A Select needed

Hi Gurus!
I have a table with 2 cols colA and colB.

The data is as follows:

colA colB
john smith
smith john

I wish to select only one of these rows, or I wish to even delete one of these rows.
How would I do it?

Thanks!

your delete statment should be like this:

------------------------------------------------------
delete from your_table t1
where rowid < (select max(rowid) from your_table t2
where
t1.colA || ' ' ||t1.colB = t2.colA || ' ' ||t2.colB
or
t1.colA || ' ' ||t1.colB = t2.colB || ' ' ||t2.colA)
;
------------------------------------------------------

Thanks a deal Shestakov!
