Обсуждение: create function problem
Hi folks, I'm writing my first plpsql function in ages and I'm going blind trying to see why it won't create. The error message and the code are below. I'm guessing it's something blindingly obvious, but can someone please point it out to me. ta Gary The actual line number is the LANGUAGE line at the end of the file. goole=# \i project_delivery_date.sql psql:project_delivery_date.sql:42: ERROR: syntax error at or near ";" LINE 37: END; ^ goole=# \q [root@stan t-cards]# cat project_delivery_date.sql -- vim: ft=sql et ai ic -- -- project_delivery_date() - project delivery date from existing dates CREATE FUNCTION project_delivery_date(date,date,date,date) RETURNS date AS $$ DECLARE eta_dealer ALIAS FOR $1; eta_customer ALIAS FOR $2; req_date ALIAS FOR $3; act_date ALIAS FOR $4; eta date; BEGIN IF act_date IS NOT NULL THEN return act_date; END IF; IF eta_dealer IS NOT NULL AND eta_customer IS NULL THEN eta:= eta_dealer; ELSE IF eta_dealer IS NULL AND eta_customer IS NOT NULL THEN eta := eta_customer; ELSE IF eta_dealerIS NULL AND eta_customer IS NULL THEN eta := NULL; ELSE IF eta_dealer > eta_customer THEN eta := eta_dealer;ELSE eta := eta_customer; END IF; IF eta IS NOT NULL AND req_date IS NULL THEN RETURN eta; END IF; IF etaIS NULL AND req_date IS NOT NULL THEN RETURN req_date; END IF; IF eta IS NULL AND req_date IS NULL THEN RETURN NULL;END IF; IF eta > req_date THEN RETURN eta; END IF; RETURN req_date; END; $$ LANGUAGE 'plpgsql'; [root@stan t-cards]# -- Gary Stainburn I.T.
