sql - ORA-00947 "not enough values"当 UPDATE 返回 BULK COLLECT INTO 用户创建类型表时

Question

尝试批量收集到表类型时出现以下错误:
ORA-00947“值不够”
我需要创建一个数据库级类型来使用我的应用程序访问结果集(打开游标)。
文件:FOO_STATUS.sql

CREATE OR REPLACE TYPE "FOO_STATUS" AS OBJECT
(
   a NUMBER,
   b NUMBER,
   c NUMBER
);
/

文件:FOO_STATUS_TABLE.sql

CREATE OR REPLACE TYPE FOO_STATUS_TABLE IS TABLE OF FOO_STATUS;
/

包裹:

PROCEDURE foo
(
  ...
)
IS
  l_foo FOO_STATUS_TABLE := FOO_STATUS_TABLE();
BEGIN
      UPDATE foo_table
      SET ...
      WHERE ...
      RETURNING foo_table_a, foo_table_b, c BULK COLLECT INTO l_foo; -- ERROR: ORA-00947

OPEN p_results FOR
    SELECT
      foo_results.a   AS a,
      foo_results.b   AS b,
      foo_results.c   AS c,
      other.d         AS d
    FROM
      TABLE( l_foo ) foo_results INNER JOIN other_table other ON foo_results.obj = other.obj
END;

Answer 1

由于 l_foo 是 的表对象 您需要将对象收集到此集合中，而不仅仅是像这样的值

returning foo_status(a, b, c) bulk collect into l_foo
