错误代码：1248 每个派生表在 MySQL 中必须有自己的别名

  • 772

我在这里遇到问题，当我尝试使用下面的查询进行选择时，我收到错误消息

错误代码：1248 每个派生表都必须有自己的别名

SELECT B.BRANCH_CODE, B.BRANCH_NAME, C.COMPANY_CODE, C.NAME, TSK.DATE_CREATE,
  CASE TB.BULK_TYPE
    WHEN 1 THEN 'Bulk Transfer'
    WHEN 2 THEN 'Bulk Payment'
    ELSE 'Payroll'
  END AS TRX_METHOD_E, 
  CASE TB.BULK_TYPE
    WHEN 1 THEN 'Bulk Transfer'
    WHEN 2 THEN 'Bulk Pembayaran Tagihan'
    ELSE 'Pembayaran Gaji'
  END AS TRX_METHOD_I,
  TB.TOTAL_RECORD,
  TB.ACCOUNT_NO,
  TSK.TRX_TOTAL,
  TC.TOTAL_CHARGE,
  DATE(TSK.DATE_TRX) AS DATE_TRX,
  TB.REF_ID,
  CASE
    WHEN TSK.TRX_COUNT_SUCCESS = TSK.TRX_COUNT_ALL THEN 'All Success'

  END AS TRX_STATUS_I  
FROM CB_TASK_BULKS TB
  JOIN CB_TASKS TSK ON TSK.REF_ID = TB.REF_ID
  JOIN CB_COMPANIES C ON C.COMPANY_ID = TSK.COMPANY_ID
  JOIN CB_BRANCHES B ON B.BRANCH_CODE = C.BRANCH_CODE,
(
  SELECT REF_ID, SUM(CHARGE) AS TOTAL_CHARGE
  FROM
  (
    SELECT XTB.REF_ID, SUM(CHARGE) AS CHARGE
    FROM CB_TRANSFERS XT
    JOIN CB_TASK_BULK_DETAILS XTBD ON XTBD.BULK_DETAIL_ID = XT.BULK_DETAIL_ID
    JOIN CB_TASK_BULKS XTB ON XTB.REF_ID = XTBD.REF_ID
    GROUP BY XTB.REF_ID

    UNION

    SELECT XTB2.REF_ID, SUM(CHARGE) AS CHARGE
    FROM CB_TRANSFERS_DOM XTD
    JOIN CB_TASK_BULK_DETAILS XTBD2 ON XTBD2.BULK_DETAIL_ID = XTD.BULK_DETAIL_ID
    JOIN CB_TASK_BULKS XTB2 ON XTB2.REF_ID = XTBD.REF_ID
    GROUP BY XTB.REF_ID

    UNION

    SELECT XTB3.REF_ID, SUM(CHARGE) AS CHARGE
    FROM CB_PAYMENTS XP
    JOIN CB_TASK_BULK_DETAILS XTBD3 ON XTBD3.BULK_DETAIL_ID = XP.BULK_DETAIL_ID
    JOIN CB_TASK_BULKS XTB3 ON XTB3.REF_ID = XTBD.REF_ID
    GROUP BY XTB.REF_ID
  )
  GROUP BY REF_ID
) TC
WHERE TC.REF_ID = TSK.REF_ID
AND (TSK.TRX_COUNT_SUCCESS > 0 OR TSK.TRX_COUNT_FAIL > 0);

有人可以帮我在这里找到我的问题吗，我想我已经为所有表提供了他自己的“名称”，例如 TB for CB_BULKS_DATA（示例）

  1. Best Answer

    您需要为 MySQL 中的所有内联视图/派生表指定一个别名，即使它们是嵌套的。在您的代码中，您在另一个派生表中使用派生表，但您似乎忘记提及内部派生表的别名。在底部的第 4 行之前放置一个别名，即GROUP BY REF_ID. 在这个 group by 子句之前放一个别名，你会没事的。

  2. 我已经解决了我的问题，

    忘记联合表上的别名只是我的错

        (
  SELECT REF_ID, SUM(CHARGE) AS TOTAL_CHARGE
  FROM
  (
    SELECT XTB.REF_ID, SUM(CHARGE) AS CHARGE
    FROM CB_TRANSFERS XT
    JOIN CB_TASK_BULK_DETAILS XTBD ON XTBD.BULK_DETAIL_ID = XT.BULK_DETAIL_ID
    JOIN CB_TASK_BULKS XTB ON XTB.REF_ID = XTBD.REF_ID
    GROUP BY XTB.REF_ID

    UNION

    SELECT XTB2.REF_ID, SUM(CHARGE) AS CHARGE
    FROM CB_TRANSFERS_DOM XTD
    JOIN CB_TASK_BULK_DETAILS XTBD2 ON XTBD2.BULK_DETAIL_ID = XTD.BULK_DETAIL_ID
    JOIN CB_TASK_BULKS XTB2 ON XTB2.REF_ID = XTBD.REF_ID
    GROUP BY XTB.REF_ID

    UNION

    SELECT XTB3.REF_ID, SUM(CHARGE) AS CHARGE
    FROM CB_PAYMENTS XP
    JOIN CB_TASK_BULK_DETAILS XTBD3 ON XTBD3.BULK_DETAIL_ID = XP.BULK_DETAIL_ID
    JOIN CB_TASK_BULKS XTB3 ON XTB3.REF_ID = XTBD.REF_ID
    GROUP BY XTB.REF_ID
  ) TTTT
  GROUP BY REF_ID
) TC

    见别名

    TTTT 高于 GROUP BY REF_ID
