Re: Can a function return more then one table?

I would like to write a function that returns one row from one table,
and about 10 rows or so from another table..

Is there a clean way to do this, or am I better off making two separate queries?

I'm thinking maybe I can use OUT parameters for the first table, and
the return value for the second table? However, I have no idea what
the syntax would be like.

what is possible

* return setof refcursors
* use arrays instead tables and returns arrays (for tables less 10000 rows)

Thanks! Both of these options sound feasible, I will play around with
some code and see what I can come up with.

One more option is to use hstore plus populate_record().
