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.
