Обсуждение: function problem plpgsql

Hi All

The following function used to work before I upgraded to 7.3.2 from 7.3.1

from some reason the delete don't delete anything :(

maybe something wrong with the delete statement ?
Can I use GET DIAGNOSTICS with the DELETE statement ?

I tried to run it by hand and it was successful.

Thanks in advance


CREATE FUNCTION forum_delete_topic(INT) RETURNS INTEGER AS '
DECLARE
return_value INTEGER;
lft_rgt forum_tree%ROWTYPE;
v_node_id ALIAS FOR $1;

BEGIN
SELECT INTO lft_rgt lft, rgt, f_id FROM forum_tree WHERE node_id =
v_node_id;

DELETE FROM forum_tree WHERE lft BETWEEN lft_rgt.lft AND lft_rgt.rgt AND
f_id = lft_rgt.f_id;

GET DIAGNOSTICS return_value = ROW_COUNT;

IF return_value < 1 THEN
 RETURN 0;
END IF;

UPDATE forum_tree
   SET lft = CASE WHEN lft > lft_rgt.lft
                  THEN lft - ( lft_rgt.rgt - lft_rgt.lft + 1 )
                  ELSE lft END,
       rgt = CASE WHEN rgt >= lft_rgt.lft
                  THEN rgt - ( lft_rgt.rgt - lft_rgt.lft + 1 )
                  ELSE rgt END WHERE rgt >= lft_rgt.lft AND f_id =
lft_rgt.f_id;

-- clone the view list_child to real dum table for speed
PERFORM mirror_forum_list_child();

RETURN return_value;

END;'
    LANGUAGE 'plpgsql';
