Hello,
I am trying to create a database trigger which inserts into a second table. I have created the following function in accordance with the reference manual documentation (7.2).
CREATE OR REPLACE FUNCTION orderinsert(INTEGER, VARCHAR) RETURNS INTEGER AS '
INSERT INTO HEXORDERS ( CUSTOMER_ID, ORDER_KEY, DISTRIBUTOR_ID, ORDER_AMOUNT, ORDER_GST ) VALUES ( $1, $2, 1, 0, 0 ) ;
SELECT 1 ;
' LANGUAGE SQL ;
It fails with the cryptic error "parse error at or near ;". Can anyone tell me what is wrong with this syntax?
Regards

You need to put your aliases in:
value1 alias for $1;
etc.

Hi Susan,
I had a similar problem with a function using pl/pgsql. I checked the docs
(7.3) for it and discovered the following info:
"A trigger procedure is created with the CREATE FUNCTION command as a function
with no arguments and a return type of OPAQUE"
http://www.postgresql.org/docs/view.php?version=7.2&idoc=1&file=plpgsql-trigger.html
Regards,
-Andreas

Hi Andrea,
That was my first attempt (i.e. using opaque) but unfortunately when I use
"opaque" it tells me that SQL functions cannot return opaque. The parse
error is also occurring on the create function statement prior to any
knowledge that the function is being used for a trigger.
Regards

I haven't followed this thread too closely, but if you are trying to use
a SQL function for a trigger, it won't work. From the docs:
(http://www.us.postgresql.org/users-lounge/docs/7.3/postgres/triggers.html)
"Trigger functions can be written in C and most procedural languages,
but not in SQL"
Try re-writing your function in PL/pgSQL. BTW, I think I saw from your
other post that you don't have PL/pgSQL installed in the database you
are using. See the createlang program or CREATE LANGUAGE statement:
http://www.us.postgresql.org/users-lounge/docs/7.3/postgres/app-createlang.html
http://www.us.postgresql.org/users-lounge/docs/7.3/postgres/sql-createlanguage.html
HTH,
Joe

I cannot see anything wrong with this syntax, except the newline in
ORDER_AMOUN\nT. But this is probably originated from your
mailing tool, isn't it?
Could you provide us with the CREATE TABLE HEXORDERS ( ... );
statement? Did you try the INSERT command within psql?

Within my postgres environment
PostgreSQL 7.2.3 on hppa-hp-hpux10.20, compiled by GCC 2.95.2
I've created table HEXORDERS and added HEXORDERS_CONSTRAINT_PK,
and did not add HEXORDERS_CONSTRAINT_FK1 nor HEXORDERS_CONSTRAINT_FK2,
because of no idea how HEXCUSTOMERS resp. HEXDISTRIBUTORS look like.
Then I did successfully
CREATE OR REPLACE FUNCTION orderinsert(INTEGER, VARCHAR) RETURNS
INTEGER AS '
INSERT INTO HEXORDERS ( CUSTOMER_ID, ORDER_KEY, DISTRIBUTOR_ID,
ORDER_AMOUNT, ORDER_GST ) VALUES ( $1, $2, 1, 0, 0 ) ;
SELECT 1 ;
' LANGUAGE SQL ;
Even a
SELECT orderinsert( 123,'abcdef' );
worked as intended (one row inserted).
Nothing about "parse error at or near ;"
So you find me pretty clueless about what's going wrong on your side.
Did you search the archives for hints on strange parser errors?

Hi Chris,
Thanks for your efforts but seems like something very odd is going on
because even though I commented out the constraints I still received the
parse errors.
I searched the archives but looked for references to triggers and functions
rather than parse errors.

Unfortunately this did not solve the problem (I tried both upper and lower
case). It is a strange one. I end up with the following 3 errors:
ERROR: parser: parse error at or near "1"
ERROR: parser: parse error at or near ";"
ERROR: parser: parse error at or near "orderinsert"

Susan,
Could you check if the SQL procedural language is available at all by
select * from pg_language ;
lanname | lanispl | lanpltrusted | lanplcallfoid | lanvalidator |
lanacl
----------+---------+--------------+---------------+--------------+--------
sql | f | t | 0 | 2248 | {=U}
internal | f | f | 0 | 2246 | {=}
c | f | f | 0 | 2247 | {=}
(3 rows)
These three should show up by default; Maybe somebody dropped it
accidentally.

Yes.
I can select from this table although the output is slightly different:
lanname | lanispl | lanpltrusted | lanplcallfoid | lancompiler
----------+---------+--------------+---------------+-------------
internal | f | f | 0 | n/a
C | f | f | 0 | /bin/cc

That's ok, it changed slightly between versions.

I think Joe is right. Try PL/pgSQL, it's much more flexible anyway.

Hi Chris,
Pleased to (finally) report success. Here are the solutions:
INSERT
---------
DROP FUNCTION orderinsert() ;
CREATE OR REPLACE FUNCTION orderinsert() RETURNS OPAQUE AS '
BEGIN
IF NEW.CUSTOMER_ID ISNULL THEN
RAISE EXCEPTION "CUSTOMER_ID cannot be NULL value" ;
END IF ;
IF NEW.CUSTOMER_SESSION ISNULL THEN
RAISE EXCEPTION "CUSTOMER_SESSION cannot be NULL value" ;
END IF ;
INSERT INTO HEXORDERS ( CUSTOMER_ID, ORDER_KEY, DISTRIBUTOR_ID,
ORDER_AMOUNT, ORDER_GST )
VALUES ( NEW.CUSTOMER_ID, NEW.CUSTOMER_SESSION, 1, 0, 0 ) ;
RETURN NEW ;
END ;
' LANGUAGE 'plpgsql' ;
DROP TRIGGER HEXCUST_TRIGGER1 ON HEXCUSTOMERS;
CREATE TRIGGER HEXCUST_TRIGGER1
AFTER INSERT ON HEXCUSTOMERS
FOR EACH ROW EXECUTE PROCEDURE orderinsert() ;
UPDATE
----------
DROP FUNCTION orderupdate() ;
CREATE OR REPLACE FUNCTION orderupdate() RETURNS OPAQUE AS '
BEGIN
IF NEW.ORDER_ID ISNULL THEN
RAISE EXCEPTION ''ORDER_ID cannot be NULL value'' ;
END IF ;
IF NEW.CUSTOMER_ID ISNULL THEN
RAISE EXCEPTION ''CUSTOMER_ID cannot be NULL value'' ;
END IF ;
UPDATE HEXORDERS
SET ORDER_AMOUNT =
SELECT SUM(CUSTITEM_QUANTITY * (ITEM_BASEPRICE +
((CUSTITEM_USERS - 1) * ITEM_USEPRICE)))
FROM HEXCUSTITEMS, HEXITEMS
WHERE HEXCUSTITEMS.CUSTOMER_ID = NEW.CUSTOMER_ID
AND HEXCUSTITEMS.ORDER_ID = NEW.ORDER_ID
AND HEXCUSTITEMS.ITEM_ID = HEXITEMS.ITEM_ID
GROUP BY HEXCUSTITEMS.ORDER_ID,
HEXCUSTITEMS.CUSTOMER_ID ),
ORDER_GST =
SELECT SUM((CUSTITEM_QUANTITY * (ITEM_BASEPRICE +
((CUSTITEM_USERS - 1) * ITEM_USEPRICE))) * .1::numeric)
FROM HEXCUSTITEMS, HEXITEMS
WHERE HEXCUSTITEMS.CUSTOMER_ID = NEW.CUSTOMER_ID
AND HEXCUSTITEMS.ORDER_ID = NEW.ORDER_ID
AND HEXCUSTITEMS.ITEM_ID = HEXITEMS.ITEM_ID
AND CUSTITEM_GST = TRUE
GROUP BY HEXCUSTITEMS.ORDER_ID, HEXCUSTITEMS.CUSTOMER_ID )
WHERE ORDER_ID = NEW.ORDER_ID
AND CUSTOMER_ID = NEW.CUSTOMER_ID ;
RETURN NEW ;
END ;
' LANGUAGE 'plpgsql' ;
DROP TRIGGER HEXCUSTITEMS_TRIGGER1 ON HEXCUSTITEMS;
CREATE TRIGGER HEXCUSTITEMS_TRIGGER1
AFTER INSERT OR UPDATE ON HEXCUSTITEMS
FOR EACH ROW EXECUTE PROCEDURE orderupdate() ;
DROP TRIGGER HEXCUSTITEMS_TRIGGER3 ON HEXCUSTITEMS;
CREATE TRIGGER HEXCUSTITEMS_TRIGGER3
AFTER DELETE ON HEXCUSTITEMS
FOR EACH ROW EXECUTE PROCEDURE orderupdate() ;
I still need to test each case but it now creates without errors. Thanks
for all your assistance.
Regards
