Hi, all


I got a problem today when I create a UDA like this. hope you guys help me solve this




CREATE OR REPLACE FUNCTION sum_fun(state int, type text) // if state type is SET or MAP , this is work
CALLED ON NULL INPUT
RETURNS int
LANGUAGE java AS 'return Integer.parseInt(type)+state;' ;


CREATE OR REPLACE AGGREGATE aggr_sum(text)
SFUNC sum_fun
STYPE int
INITCOND {};




error message:
InvalidRequest: code=2200 [Invalid query] message="Invalid set literal for (aggregate_initcond) of type int"
