SRF problem

[Együd Csaba]

Hi All,
I'd like to write an SRF but I'm block a strange error message

WARNING: plpgsql: ERROR during compile of check_close2 near line 11
ERROR: return type mismatch in function returning tuple at or near ";"

I get this message even if the return rowset contains 0 or more tuples. What
is done wrong?
The code:
-----------------------------------------------------------------
create type CHECK_CLOSE as (
prooftype text,
id int,
sn text,
partnername text,
performancedate text,
detailcount int
);
------------------------------------------------------------------
create or replace function check_close2() returns CHECK_CLOSE AS '
declare
R CHECK_CLOSE%ROWTYPE;
begin
R.prooftype := ''INCINV'';
R.id := 1;
R.sn := ''012334'';
R.partnername := ''someone'';
R.performancedate := ''2004.02.01'';
R.detailcount := 0;
return next R;
return;
end;'
language 'plpgsql';
------------------------------------------------------------------
select * from check_close2();
WARNING: plpgsql: ERROR during compile of check_close2 near line 11
ERROR: return type mismatch in function returning tuple at or near ";"
Thank you very much.

This should be SET OF CHECK_CLOSE, remember you're calling the function like:
SELECT * FROM check_close2()
rather than:
SELECT check_close2()

So the return-type needs to be "set of" even if only returning one value.

Hi,

create or replace function check_close2() returns CHECK_CLOSE AS '

"return next" needs sets as a return type.

create or replace function check_close2() returns setof check_close ...
^^^^^

should work.

Mit freundlichem Gruß / With kind regards
