Question

在下面的查询中有什么错误，它的抛出错误SQL错误：ORA-00933：SQL命令没有正确结束 00933. 00000 - ＆＃34; SQL命令未正确结束＆＃34;。想要从两个与ERROR_LOG err_payment_id匹配的表中删除所有payment_ids 请帮我纠正查询。

TBLPAYMENT(PAYMENT_ID, OTHER COLUMNS)
TBLPAYMENT_ALT_ID (PAYMENT_ID, OTHER COLUMNS)
ERROR_LOG(ERR_PAYMENT_ID, OTHER COLUMNS)

    DELETE TBLPAYMENT, TBLPAYMENT_ALT_ID FROM TBLPAYMENT PYMT INNER JOIN 
    TBLPAYMENT_ALT_ID PAI ON PYMT.PAYMENT_ID = PAI.PAYMENT_ID 
    WHERE PYMT.PAYMENT_ID IN (SELECT ERR_PAYMENT_ID FROM ERROR_LOG);

Answer 1

Oracle中需要2个delete语句。

DELETE TBLPAYMENT PYMT WHERE PYMT.PAYMENT_ID IN (SELECT ERR_PAYMENT_ID FROM ERROR_LOG);

DELETE TBLPAYMENT_ALT_ID PAI WHERE PAI.PAYMENT_ID IN (SELECT ERR_PAYMENT_ID FROM ERROR_LOG);

Answer 2

您无法使用SQL Server中的Join进行删除。此外，您无法使用常规删除一次从多个表中删除。相反，Make it 2 delete语句如下：

DELETE FROM TBLPAYMENT
       WHERE EXISTS
       (      
          SELECT 1 FROM ERROR_LOG WHERE ERR_PAYMENT_ID = TBLPAYMENT.PAYMENT_ID
       )
DELETE FROM TBLPAYMENT_ALT_ID
       WHERE EXISTS
       (      
          SELECT 1 FROM ERROR_LOG WHERE ERR_PAYMENT_ID = TBLPAYMENT_ALT_ID.PAYMENT_ID
       )

Answer 3

试试这个 -

DELETE from TBLPAYMENT where PAYMENT_ID in (select PYMT.PAYMENT_ID FROM TBLPAYMENT PYMT INNER JOIN 
TBLPAYMENT_ALT_ID PAI ON PYMT.PAYMENT_ID = PAI.PAYMENT_ID 
WHERE PYMT.PAYMENT_ID IN (SELECT ERR_PAYMENT_ID FROM ERROR_LOG))

DELETE from TBLPAYMENT_ALT_ID where PAYMENT_ID in (select PAI.PAYMENT_ID FROM TBLPAYMENT PYMT INNER JOIN 
TBLPAYMENT_ALT_ID PAI ON PYMT.PAYMENT_ID = PAI.PAYMENT_ID 
WHERE PYMT.PAYMENT_ID IN (SELECT ERR_PAYMENT_ID FROM ERROR_LOG))

如何用内连接和子查询
