Thanks Sean. I'm trying the following after having done the import.
CREATE function set_sequence_ids() RETURNS INTEGER AS '
DECLARE
arg INTEGER;
BEGIN
select into arg max(id) from foo;
select setval('foo_id_seq', 10);
return arg;
END;
' LANGUAGE 'plpgsql';
DECLARE
arg INTEGER;
BEGIN
select into arg max(id) from foo;
select setval('foo_id_seq', 10);
return arg;
END;
' LANGUAGE 'plpgsql';
I get the following error in psql.
psql:func.sql:9: ERROR: syntax error at or near "foo_id_seq" at charact
er 152
psql:func.sql:9: LINE 6: select setval('foo_id_seq', 10);
psql:func.sql:9: ^
er 152
psql:func.sql:9: LINE 6: select setval('foo_id_seq', 10);
psql:func.sql:9: ^
setval seems to work okay outside plpgsql but I need it to do the select into.
Any help is greatly appreciated.
Thanks,
Hari
