Thread: sequences in functions

I am having problems referencing sequeces in a function, I think because of
the '' characters. The function I am creating is a follows: -

CREATE FUNCTION InsertClient ( varchar, varchar, varchar, varchar, varchar,
varchar ) RETURNS int4 AS '
DECLAREid INT;
BEGINSELECT nextval('client_seq') INTO id;
INSERT INTO client (client_id, last_name, address1, country)VALUES (id, $1, $2, $3);
INSERT INTO client_card (client_card_id, type, number, expiry_date,
client_id)VALUES (nextval('client_card_seq'), $4, $5, $6, id);
RETURN id;
END;
' LANGUAGE 'plpgsql';


And the error message is

ERROR:  parser: parse error at or near "client_seq"
EOF


Is this because of the ' ' ???

Also can you pass in a array or hash to the function?

Cheers

Graham

You must to use two quotes:

SELECT nextval(''client_seq'') INTO id;

I have noticed that you can only pass 16 parameters to a function, I was
therefore wondering how you can do atomic inserts (such as the function
below but with more params) using pl/pgsql if you can't pass complex data
types. Is this something that transactions are not used for or is it best
done as two seperate calls in my perl scripts?
