Hi all.
I created a function, using EMS:
CREATE OR REPLACE FUNCTION "geo_schema"."search_geo" () RETURNS SETOF
varchar AS
$body$
declare x_longlat cursor for select long_lat from h2s ;
declare var_longlat public.geometry ;
declare x_id varchar ;
begin
open x_longlat ;
<<loop1>>
loop
fetch x_longlat into var_longlat ;
if not found then
close x_longlat ;
exit ;
end if ;
select field_id from geo_table
where within(var_longlat, geo_polygon) limit 1 into x_id ;
if x_id <> '' then
return next x_id ;
end if ;
end loop ;
end ;
$body$
LANGUAGE 'plpgsql' VOLATILE CALLED ON NULL INPUT SECURITY INVOKER;
When I debug it (using EMS tools), it works fine, and I get 73 rows, but
when I run it like:
select * from search_geo() ;
I get the error: ERROR: control reached end of function without RETURN
What can be wrong?
TIA
Ignacio.

You don't have a RETURN statement.

Thanks Tom.
I didn't know I needed a RETURN statement at the end. I assumed that the
"return next" statement would be enough. It works fine now.

Hi Support,
I get an error in a stored procedure - not a stored function mind you -
control reached end of function without RETURN
The error occurs when doing an exit <label> in a stored procedure. Now
I cannot give all of the stored procedures involved but I can simulate
te problem with a very simple block:
DO
$BODY$
<<simple_block>>
BEGIN
begin
exit simple_block;
-- for demo purposes
raise notice '%', 'unreachable!';
end;
raise notice '%', 'End of block';
end;
$BODY$
This will return the error on Postgres version 13, Version 12 and 9.
Now I thought this was text-book behaviour of exiting a code block. I do
not like programming this way but it is part of a migration project of
Oracle to PG.
What do I miss ?
Kind regards,
If you put this code snippet in a file and execute like:
postgres@herwig-NUC10i7FNH:~$ psql -f do_test.sql
psql:do_test.sql:12: ERROR: control reached end of function without RETURN
CONTEXT: PL/pgSQL function inline_code_block

This is Postgres's bug
You can use an just workaround - extra outer block BEGIN END;

Yeah, agreed. Looks reasonably simple to fix, though.
