Обсуждение: retrieving specific info. from one column and locating it in another

I'm trying to retrieve some info from one column and
put it in another.  I have a column that has a bunch
of information in it called 'Route'.  I don't need to
show all of that information.  Instead I need divide
that single column into two seperate columns called
'Sender' and 'Receiver'.  How do I divide this
information up into these two columns.  I know of
methods called charindex and patindex.  I need to do
something like that but instead of returning the
position of the info, to just return the selected
info.    
Ex)  I have a column named Route....with info in it
similar to 'UPS NS  Ground'      How do I create a second column called
'Delivery' and pull only the 'NS' out of the Route
column and put it into the 'Reciever' column?      Similarly how would I pull just the UPS part
out of Route and put it into 'Sender'?


thanks,
Marc

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.
