I've got this function which works off a trigger.
The trigger is calling the function ok, but I get this error.
<error>
NOTICE: plpgsql: ERROR during compile of mon_sum_update near line 43
ERROR: parse error at or near ""
Now line 43 is this either the return null or end statement at the end of
the function...
RETURN NULL;
END
Can anyone see what I've done wrong in there?
TIA
Geoff
Here is my trigger and function.
trigger
======
CREATE TRIGGER doc_status_trig AFTER UPDATE ON document_status FOR EACH ROW
EXECUTE PROCEDURE mon_sum_update()
function
======
CREATE FUNCTION mon_sum_upd () RETURN OPAQUE AS '
BEGIN
-- Ensure we have a record that is valid .
IF ( ! NEW.direction && NEW.direction && NEW.msgtype && NEW.status )
THEN
RETURN NULL;
-- Ensure the record exists in the monitor_summary table.
IF ( ! EXISTS SELECT * FROM monitor_summary WHERE unit = NEW.unit and
msgtype = NEW.msgtype and direction = NEW.direction and status =
NEW.status )
THEN
INSERT INTO monitor_summary ( version, cdate, mdate, direction, unit,
msgtype, status ) VALUES ( 1, 'now', 'now', 'NEW.direction', 'NEW.unit',
'NEW.msgtype', 'NEW.status' );
-- Ensure OLD and NEW status's are different.
IF ( NEW.status == OLD.status )
THEN
RETURN NULL;
-- Update the OLD status record. ( -1 )
UPDATE monitor_summary
SET
total = total - 1
WHERE
direction = OLD.direction AND unit = OLD.unit AND msgtype = OLD.msgtype AND
status = OLD.status ;
-- Update the NEW status record. ( +1 )
UPDATE monitor_summary
SET
total = total + 1
WHERE
direction = OLD.direction AND unit = OLD.unit AND msgtype = OLD.msgtype AND
status = NEW.status ;
RETURN NULL;
END
' LANGUAGE 'plpgsql' ;
I'm using pgAdminII to insert this function, and it goes in ok..
