Hi,
I want to write a function of the following type
CREATE FUNCTION test ( <scalar form type> )
RETURNS setof MyTable
AS
'SELECT * FROM MyTable WHERE id IN $1'
LANGUAGE 'SQL' ;
I was not able to find a reference whether this is possible and if yes
how to specify the argument type and how to call this function to hand over
the list for the IN clause correctly.
Next question. Is there any example how to return a SETOF MyTable in
a plpgsql function? I tried
CREATE FUNCTION test2()
RETURNS setof MyTable
AS '
DECLARE
result SETOF MyTable ;
BEGIN
result := (SELECT * FROM MyTable);
RETURN result ;
END; ' LANGUAGE 'plpgsql';
wich failed.
Kind regards
Andreas.
