如何获取SQL Server 2000查询中的当前行号？

Question

如何使用ROW_NUMBER()不支持该功能的SQL Server 2000在SQL查询中获取行号？

您始终可以尝试将临时表与标识列一起使用

DECLARE @table TABLE(
        [id] INT IDENTITY(1,1),
        Val VARCHAR(10)
)

DECLARE @TableFrom TABLE(
        Val VARCHAR(10)
)
INSERT INTO @TableFrom (Val) SELECT 'A'
INSERT INTO @TableFrom (Val) SELECT 'B'
INSERT INTO @TableFrom (Val) SELECT 'C'
INSERT INTO @TableFrom (Val) SELECT 'D'

INSERT INTO @table (Val) SELECT * FROM @TableFrom ORDER BY Val DESC
SELECT * FROM @table

我在Sql Server 2000中看到的一些最好的分页使用了这种模式

DECLARE @PageStart INT,
        @PageEnd INT

SELECT  @PageStart = 51,
        @PageEnd = 100

SELECT  <TABLE>.*
FROM    (
            SELECT  TOP (@PageStart - 1)
                    <ID>
            FROM    (
                        SELECT  TOP (@PageEnd)
                                <ID>
                        FROM    TABLE
                        ORDER BY <ID> ASC
                    ) SUB
            ORDER BY SUB.<ID> DESC
        ) SUB INNER JOIN
        <TABLE> ON SUB.<ID> = <TABLE>.<ID>
ORDER BY SUB.<ID>
