I am trying to figure out how to return more than one field using "SETOF".
I can concatenate the fields in the select statement down to one and use SETOF Text to return them, then split them back apart in my code. This is a bit kludgy though. I would rather do this the most correct and efficient way possible. In most RDBMS you can easily deal with multiple columns in server side procedures that contain a SELECT, but I can find nothing about how to do this in PostGreSQL Documentation or anywhere else.
How can you do this with PostGreSQL? If you can, is it better to do this this way, or better to put the query inline in the code?
Testing has shown that doing it this way using SETOF with a server side function is only marginally faster. I have the feeling that if I didn't have to concatenate, then split the results, that that margin would increase from 9% faster (@50 users, 20 records, 7 fields) to much faster than 9%.
