Question

我正在更新temp_docmeta表中的xprojecttype，并尝试通过包含"d.xproject_id NOT IN"子句来忽略我的下方查询中的所有无效数字，但它仍然会引发01722. 00000 - "invalid number"错误

BEGIN
  FOR X IN
  (SELECT projecttype,pid,enddate FROM temp_project
  )
  LOOP
    UPDATE temp_docmeta d
    SET d.xprojecttype     =X.projecttype
    WHERE d.xproject_id    =X.PID
    AND X.projecttype     IS NOT NULL
    AND X.enddate          > '10-MAR-14 00.00.00'
    AND d.xproject_id NOT IN
      (SELECT TO_NUMBER(xproject_id)
      FROM temp_docmeta
      WHERE REGEXP_LIKE(xproject_id, '[^0-9]+')
      );
  END LOOP;
END ;

但是当我用delete语句删除同一组记录然后运行上面的更新命令时，它工作正常。

DELETE
FROM temp_docmeta
WHERE xproject_id IN
  (SELECT xproject_id
  FROM temp_docmeta
  WHERE REGEXP_LIKE(xproject_id, '[^0-9]+')
  );

我不想从temp_docmeta表中删除上述记录，但需要像第一次查询一样更新temp_docmeta表。我该怎么办？

Answer 1

您的查询尝试更改TO_NUMBER您不想要的所有值

也许你应该尝试

 AND d.xproject_id IN
  (SELECT TO_NUMBER(xproject_id)
  FROM temp_docmeta
  WHERE NOT REGEXP_LIKE(xproject_id, '[^0-9]+')
  );

但这取决于订单，如何完成TO_NUMBER和REGEXP_LIKE

Answer 2

我更改了X.PID的数据类型，如下所示，to_char并且它有效，但是，当我将xproject_id的数据类型更改为“to number”时，它没有用。奇怪。不是吗？或者我错过了什么？

BEGIN
  FOR X IN
  (SELECT projecttype,pid,enddate FROM temp_PROJECT where projecttype IS NOT NULL
  AND enddate      > '10-MAR-14 00.00.00'
  AND PID NOT LIKE '-1'
  )
  LOOP
    UPDATE temp_docmeta
    SET xprojecttype     =X.projecttype
    WHERE xproject_id    =to_char(X.PID)
    AND xproject_id in
      (SELECT UNIQUE(xproject_id)
      FROM temp_docmeta
      WHERE REGEXP_LIKE(xproject_id, '[0-9]+')
      );
  END LOOP;
END;
