Question

对于大约5,000-10,000行的表，使用SQL Server 2005的最有效的分页解决方案是什么？我见过几个，但没有比较它们。

Answer 1

对于大小的表，使用公用表表达式（CTE）和ROW_NUMBER;使用一个小函数来计算要根据@PageNumber和@PageSize变量（或任何你想要调用的变量）返回的记录。我们的一个存储过程的简单示例：

-- calculate the record numbers that we need

DECLARE @FirstRow INT, @LastRow INT
SELECT  @FirstRow   = ((@PageNumber - 1) * @PageSize) + 1,
        @LastRow    = ((@PageNumber - 1) * @PageSize) + @PageSize

;
WITH CTE AS
(
    SELECT [Fields]
           , ROW_NUMBER() OVER (ORDER BY [Field] [ASC|DESC]) as RowNumber 
    FROM [Tables]
    WHERE [Conditions, etc]
)
SELECT * 
       -- get the total records so the web layer can work out
       -- how many pages there are
       , (SELECT COUNT(*) FROM CTE) AS TotalRecords
FROM CTE
WHERE RowNumber BETWEEN @FirstRow AND @LastRow
ORDER BY RowNumber ASC

我读过的各种分页技术的最佳讨论之一是：SQL Server 2005 Paging – The Holy Grail。您必须在SQLServerCentral.com上完成免费注册才能查看该文章，但这非常值得。

Answer 3

即使这应该有帮助..

SELECT * FROM 
( 
    SELECT Row_Number() OVER(order by USER_ID) As RowID,
    COUNT (USER_ID) OVER (PARTITION BY null) AS TOTAL_ROWS, 
    select name from usertbl
) 
As RowResults WHERE 
RowID Between 0 AND 25

不确定它是否优于@keith版本。
