Hi Carl!

Did you try "select field1, field2 from senators()" ?


I'm using pg 8.0 here with a function like this, for Npgsql tests:

create function funcB() returns setof tablea as '
select * from tablea;
' language 'sql';


And I can do:

npgsql_tests=> select * from funcb();
 field_serial |        field_text        | field_int4 | field_int8 |
field_bool
