Обсуждение: Error in declaring %rowtype for recurrence
Dear Friends,
Postgres 7.3.4 on RH Linux 7.2
I am having an table name recurrence under the schema crm. While I refer it as %rowtype I have error msgs.
CREATE OR REPLACE FUNCTION crm.fn_rowtypetest() RETURNS varchar AS
'DECLARE
rec_recurrence crm.recurrences%rowtype;
BEGIN
FOR rec_recurrence IN SELECT * FROM crm.recurrences LOOP
RAISE NOTICE 'Hai';
END LOOP;
RETURN 'DONE';
END;'
LANGUAGE 'plpgsql' VOLATILE;
'DECLARE
rec_recurrence crm.recurrences%rowtype;
BEGIN
FOR rec_recurrence IN SELECT * FROM crm.recurrences LOOP
RAISE NOTICE 'Hai';
END LOOP;
RETURN 'DONE';
END;'
LANGUAGE 'plpgsql' VOLATILE;
while I execute
select crm.fn_rowtypetest()
WARNING: plpgsql: ERROR during compile of fn_rowtypetest near line 0
ERROR: cache lookup for type 0 of recurrences.........pg.dropped.16........ failed
The same function works if I declare that via an record type
CREATE OR REPLACE FUNCTION crm.fn_rowtypetest() RETURNS varchar AS
'DECLARE
rec_recurrence record; ------------------------------------------------------------------------------------------ Note the change here
BEGIN
FOR rec_recurrence IN SELECT * FROM crm.recurrences LOOP
RAISE NOTICE 'Hai';
END LOOP;
RETURN 'DONE';
END;'
LANGUAGE 'plpgsql' VOLATILE;
'DECLARE
rec_recurrence record; ------------------------------------------------------------------------------------------ Note the change here
BEGIN
FOR rec_recurrence IN SELECT * FROM crm.recurrences LOOP
RAISE NOTICE 'Hai';
END LOOP;
RETURN 'DONE';
END;'
LANGUAGE 'plpgsql' VOLATILE;
Why is that so? Anyone can please clear me.
Regards
Kumar

PG 7.4 is a little better at dealing with dropped columns in plpgsql
rowtypes.
