oracles嵌套表中的最大行数是多少

Question

CREATE TYPE nums_list AS TABLE OF NUMBER;

oracle的嵌套表中可能的最大行数是多少？

UPDATE

CREATE TYPE nums_list  AS TABLE OF NUMBER;

CREATE OR REPLACE  FUNCTION  generate_series(from_n NUMBER, to_n NUMBER)
RETURN nums_list AS
ret_table nums_list := nums_list();
BEGIN

  FOR i IN from_n..to_n LOOP
    ret_table.EXTEND;
    ret_table(i) := i;
  END LOOP;
  RETURN ret_table;

END;


SELECT count(*)   FROM TABLE ( generate_series(1,4555555) );

这给出了错误: ORA-22813 operand value exceeds system limits, Object or Collection value was too large

Answer 1

的下标为嵌套表的范围为1..2 31所以可以有2个集合中的31个元素.这个限制至少从8.1.6没有变化,当然,它可能会在未来发生变化.
