Don’t understand the logic either. I am just maintaining the system. Threw up the internal error for the first time after being in production for nearly 4 years, so that is how I came to notice the SQL.

Thanks anyway for your replies.

TIA,
Actually, you can group by a column that isn’t in your select; however it may result in exact duplicates in your result set. In your case, you handled this through the use of ‘distinct’. Not sure the purpose of your distinct and then grouping to a further detail level–doesn’t seem logical to me.

I notice that your original sql had no select columns that were a ‘group by’ expression, such as count or sum. distinct isn’t a group by expression. I’m surprised that SQL*Plus was running it ok.

1) can’t group by a column you don’t reference
2) the distinct may return more than one value
