It fetches about 20 rows from a table of approx 4 million, then it needs to do further calculations to narrow them down further. Previously we have only written database code for SQL Server, and there we would use a table variable. Apparently temporary tables are not equivalent and not suitable for this.


Seems like a temp table with a insert into would work for you.

insert into mytemptable
(field1,field2)
select field1,field2 from sometable where field1 = 5;

Then you can query the new temp table anyway you would like while you are still in the function.
