Tsql 带的t-sql

我必须用query进行查询，比如

; WITH #table1  
(  
SELECT id, x from ... WHERE....  
UNION ALL  
 SELECT id, x from ... WHERE...  
)  

WITH #table2  
(  
 SELECT DISTINCT tbl_x.*,ROW_NUMBER() OVER (order by id) as RowNumber  
WHERE id in ( SELECT id from #table1)  
)  

SELECT * FROM #table2 WHERE RowNumber > ... and ...

---

因此，我必须使用WITH on WITH，然后选择on second WITH，如何操作？

您可以通过用逗号分隔每个CTE，在

WITH

关键字之后定义多个CTE

WITH T1 AS
(
    SELECT id, x from ... WHERE....
    UNION ALL
    SELECT id, x from ... WHERE...
)
, T2 AS
(
    SELECT DISTINCT tbl_x.*, ROW_NUMBER() OVER (order by id) as RowNumber
    WHERE id in ( SELECT id from T1 )
)
SELECT * FROM T2 WHERE RowNumber > ... and ...
