Thread: Returning result sets.

How do I declare a stored function to return a result set. (ie set of records)

I can define a function returning " setof record "
but I get an error:

A column definition list is required for functions returning RECORD

The docs(7.3)  seem to think that this should be ok.
so what is wrong?

I have managed to get it to work by first declaring a type for the record set:

CREATE TYPE sp_report_retail_sales_type AS (a int8, b int8, c numeric, d numeric);

TIA,

You need to look a bit closer at the docs ;-)

After declaring myfunc() to return setof record, try:

select * from my_func() AS (a int8, b int8, c numeric, d numeric);
                         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                           missing - "the column definition list"
HTH,
