更新语句中的DBMS_SQL.NUMBER_TABLE引发无效数据类型错误

为什么选择有效但更新会抛出无效数据？

DECLARE
    L_NUMBER NUMBER;
    L_NUMBER_TABLE DBMS_SQL.NUMBER_TABLE;
    L_LAST_PRINTED_DATE DATE := SYSDATE;
BEGIN
    L_NUMBER_TABLE(0) := 1033000;

-- THIS WORKS
SELECT TB.COLUMN_VALUE
INTO L_NUMBER
FROM TABLE(L_NUMBER_TABLE) TB;

-- THIS DOES NOT WORK
--  ERROR AT LINE 1
--  ORA-00902: INVALID DATATYPE
--  ORA-06512: AT LINE 13
UPDATE SCHEMA.REAL_NUMBER_TABLE
SET    REAL_NUMBER_DATE           = L_LAST_PRINTED_DATE
WHERE  EXISTS (  SELECT TB.COLUMN_VALUE
                    FROM TABLE( L_NUMBER_TABLE ) TB
                    WHERE TB.COLUMN_VALUE = REAL_NUMBER_COLUMN );


END;

我试图通过游标循环并更新在游标中找到的主要序列的最后打印日期。我尝试通过游标循环，但是当我将游标返回给客户端时，它抛出索引不足错误。因此，我不得不创建两个游标，一个游标循环，另一个游标返回。我的目标是学习保存用于更新表的集合的最简单，最可维护的方法。

当前，内联单个sql更新语句有效，但需要在SQL和PLSQL引擎之间进行多个引擎跃点。为什么允许我进行选择但不更新我的号码表？

数据库版本：12.1.0.2.0

DBMS_SQL.NUMBER_TABLE是在DBMS_SQL包中定义为以下内容的PL / SQL关联数组：

TYPE number_table IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;

CREATE TABLE real_number_table ( real_number_column, real_number_date ) AS
  SELECT 1033000, DATE '2019-01-01' FROM DUAL;

CREATE TYPE number_table IS TABLE OF NUMBER;

DECLARE
  L_NUMBER NUMBER;
  L_NUMBER_TABLE NUMBER_TABLE;
  L_LAST_PRINTED_DATE DATE := SYSDATE;
BEGIN
  L_NUMBER_TABLE := NUMBER_TABLE();
  L_NUMBER_TABLE.EXTEND;
  L_NUMBER_TABLE( L_NUMBER_TABLE.COUNT ) := 1033000;

  UPDATE REAL_NUMBER_TABLE
  SET    REAL_NUMBER_DATE = L_LAST_PRINTED_DATE
  WHERE  EXISTS (
    SELECT TB.COLUMN_VALUE
    FROM TABLE( L_NUMBER_TABLE ) TB
    WHERE TB.COLUMN_VALUE = REAL_NUMBER_COLUMN
  );
END;
/

SELECT * FROM real_number_table;

REAL_NUMBER_COLUMN | REAL_NUMBER_DATE
-----------------: | :---------------
           1033000 | 09-OCT-19  

DECLARE
  L_NUMBER NUMBER;
  L_NUMBER_TABLE NUMBER_TABLE := NUMBER_TABLE( 1033000 );
  L_LAST_PRINTED_DATE DATE := SYSDATE + 1;
BEGIN
  UPDATE REAL_NUMBER_TABLE
  SET    REAL_NUMBER_DATE = L_LAST_PRINTED_DATE
  WHERE  REAL_NUMBER_COLUMN MEMBER OF L_NUMBER_TABLE;
END;
/

SELECT * FROM real_number_table;
