[GENERAL] return setof and Temp tables

[Justin B. Kay]

I have looked around and found that you can use return setof in a function to return a result set, but can you use a temp table as the setof target?  I build a temp table using various select statements and then try to return the result as a recordset.  I get an error: type t1 does not exist.   If this is not possible, is there some alternative way to do this?  I am trying to translate what was done in a ms sql database.   Justin
