Question

我对链接服务器有一个SELECT语句，如下所示；

SELECT [TrackingId]
FROM  [Server1\DB].[sctracking].[dbo].[scTracking] AS A
WHERE EXISTS (SELECT * FROM [Server2\DB].[sctracking].[dbo]. [scTracking] AS B
WHERE A.Reserved = B.Reserved )

这给了我想要的输出，但是实际上我想要做的就是删除结果。

谁能建议我将删除语句包装到其中吗？

Answer 1

DELETE A FROM [Server1\DB].[sctracking].[dbo].[scTracking] A
WHERE EXISTS (SELECT *
              FROM [Server2\DB].[sctracking].[dbo]. [scTracking] AS B
WHERE A.Reserved = B.Reserved)

Answer 2

改为使用DELETE语句：

DELETE A
FROM [Server1\DB].[sctracking].[dbo].[scTracking] AS A
WHERE EXISTS (SELECT 1 
              FROM [Server2\DB].[sctracking].[dbo].[scTracking] AS B
              WHERE A.Reserved = B.Reserved 
             );
