Question

如何在SQL2005上对此查询应用偏移量？

SELECT [name],[phone] 
FROM (
      SELECT *,Row_Number() Over (Partition By phone Order By (Select Null)) AS RN
      FROM Table1
      ) AS T
Where RN = 1

Answer 1

mssql 2005不支持

OFFSET，但您可以使用以下approuch来执行此操作。如果您要选择从按名称排序的90到100之间的10条记录，则可以使用以下查询

;with data as
(
    SELECT [name],[phone] 
    FROM (
      SELECT *,Row_Number() Over (Partition By phone Order By (Select Null)) AS RN
      FROM Table1
      ) AS T
    Where RN = 1
)
select * from 
    (   select top(10) * from 
            (   select top(100) * from data order by name asc ) 
        t1 order by name desc 
    ) t2 order by name

Answer 2

我自己解决了这个问题。我使用此查询（具有不同的列名称）

with CTE as (
   SELECT cFullname,BuyerPhoneNumber 
    FROM (
      SELECT *,Row_Number() Over (Partition By BuyerPhoneNumber Order By (Select Null)) AS RN
      FROM [Order]
      ) AS T
    Where RN = 1
)
SELECT * 
FROM (
SELECT  Row_Number() OVER (ORDER BY cFullname ASC) AS CI_offset_row_number, *
FROM CTE
) AS A 
WHERE A.CI_offset_row_number BETWEEN (21) AND (30)

SQL SERVER 2005 OFFSET
