如何将包含except的select语句转换为Ordered表？

Question

以下是我的例子：

select * into temp from 
      select *, 'I' as flag from (
            select * from A
            except 
            select * from B ) a
      union
      select *, 'D' as flag  from (
            select * from B
            except 
            select * from A ) b
ORDER BY X1,X2

Answer 1

这是答案 -

从*中选择*到dbo.temp       （选择*，＆＃39;我作为标志来自（             从dbo.A中选择*             除了             从dbo.B中选择* a       联盟       选择*，＆＃39; D＆＃39;作为旗帜（来自             从dbo.B中选择*             除了             从dbo.A中选择* b ）作为C. 按X1，X2排序

- 使用后删除临时表 DROP TABLE temp
