Hi I'm passing this on second hand so forgive me if I'm a bit vague...
My boss is trying to write a function in PL/pgsql that manipulates a small, temporary set of data. 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.
The closest I've come from reading the docs is functions that return SETOF. However I can't see any way to query the result set like a table. Can anyone offer any hints/links?
