Hi all. Was working tonight and ran into the following error. Doing a
union between two selects (to get around the lack of outer joins - hint
hint), I was getting the error:
ERROR: Each UNION clause must have the same number of columns
Upon examining the SQL statement in question, I verified that it did,
indeed, have the same number of columns. After some fiddling, I found the
actual problem was that I was doing an ORDER BY on a column which was not
being included in the two select statements. Unfortunately, the error
message wasn't pointing at that.
I'm not sure if this is just a simple change or implies other problems
with the parser but I thought I'd toss it out onto the pile.
Cya...
