commit within a procedure loop - cannot commite with subtransaction - Mailing list pgsql-general

Hi,

Using a procedure for the first time to run some processing for each row in
a table, generating output to a target table. The following works without
COMMIT the example below gives:

INFO: Error Name:cannot commit while a subtransaction is active
INFO: Error State:2D000

Could someone point me in the right direction so i can understand why and
how i might rework my methodology?


CREATE OR REPLACE PROCEDURE my_functions.first_procedure(
    )
LANGUAGE 'plpgsql'

AS $BODY$

DECLARE

grd_geom geometry(Polygon,27700);
grd_gid integer;
rec data.areas%rowtype;

BEGIN

DELETE FROM data.output;
DELETE FROM data.temp_output;

FOR rec IN SELECT * FROM data.areas
    LOOP
        grd_geom := rec.geom;
        grd_gid := rec.gid;

        PERFORM my_functions.processing_function(grd_geom);
        DELETE FROM data.temp_output;
        COMMIT;
    END LOOP;
RETURN;
                                             

END;

$BODY$;

GRANT EXECUTE ON PROCEDURE my_functions.first_procedure() TO postgres;
GRANT EXECUTE ON PROCEDURE my_functions.first_procedure() TO PUBLIC;

Thanks

Andy
