The problem:
I've two tables, both called "test" on two different schemas, let's say
schema1 and schema2.
I need to write a function like (just a simple example)
CREATE OR REPLACE FUNCTION foo()
RETURNS int4 AS
$BODY$
declare
num int4;
begin
select into num count(*) from test;
return num;
end;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
I need something like:
SET search_path = schema1,public;
select foo();
-- get the number of rows of schema1.test
SET search_path = schema2,public;
select foo();
-- get the number of rows of schema2.test
The problem is that i get always the number of rows from the table in
the schema that was current when I created the function.
How can I obtain what I need ?? I cannot write 2 different functions (my
db is really more complex, with lots of functions and triggers that need
this kind of access).
Thanks to everybody
