Question

我正在尝试对本地Access表运行此删除查询，但是我收到错误消息

无法从指定的表中删除

请提供正确的SQL来复制和粘贴。

非常感谢你，Nathaniel

DELETE RO.*, RO.STATUS, CO.ID, CO.PRINTED_DATE
FROM tmpReleasedOrders AS RO 
LEFT JOIN SYSADM_CUSTOMER_ORDER AS CO ON RO.orderID = CO.ID
WHERE (((RO.STATUS)="C" Or (RO.STATUS)="X")) OR (((CO.ID) Is Null)) OR (((CO.PRINTED_DATE) Is Null));

Answer 1

此查询取决于SYSADM_CUSTOMER_ORDER在ID上具有唯一索引。

DELETE ro.*
FROM tmpReleasedOrders AS ro
LEFT JOIN SYSADM_CUSTOMER_ORDER AS CO 
ON RO.orderID = CO.ID
WHERE RO.STATUS="C" Or RO.STATUS="X" OR CO.ID Is Null OR CO.PRINTED_DATE Is Null

如果您没有SYSADM_CUSTOMER_ORDER的索引，可以在这些行上使用某些内容：

DELETE tmpreleasedorders.*
FROM tmpreleasedorders
WHERE  status IN ( "c", "x" )
OR orderid IN (
   SELECT orderid
   FROM   tmpreleasedorders AS ro
   LEFT JOIN sysadm_customer_order AS CO
   ON RO.orderid = CO.id
   WHERE  CO.id IS NULL
   OR CO.printed_date IS NULL)

删除查询错误消息“无法从指定的表中删除”
