The only way I am aware of achieving this is by using the mail system you can then play around with the
results as strings or whatever you want. You have to put in some extra code if the query results exeed 255
If you want to retain the results
create table (#)dumpheader
xp_findnextmsg (parameters) 'get id of next message
xp_readmail (parameters) 'set peek to true which leaves it as unread
(any other parameters) ' with peek set to false
' some code to prevent infinite loop if message never arrives
You could do this sort of thing with any results and handle a whole range of different mail subjects which
can be sent from stored procs or any mail user on the network.
The 'reciever' could run continually searching for the mail messages and the sending proc could wait for
the appropriate table entries to appear.
With some good defensive coding it could work quite well.
