Marc,
I've seen some tricky stuff to split column values yesterday on the
list.
It was sent by Peter Childs Subject Re: [SQL] Question on SQL and
pg_-tables.
He found something like a split.
Adapted to your needs it would result in something similar to (supposed
blanks are your separators)
SELECT SUBSTRING(route,1,POSITION(' ' IN route)-1) AS ups,
SUBSTRING(route,POSITION(' ' IN route)+1,POSITION(' ' IN
SUBSTRING(route,POSITION(' ' in ROUTE)+1))) AS ns
FROM ...
Hope this helps.
Regards, Christoph
