使用SQL Server 2005的最佳分页解决方案？

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基于@PageNumber和@PageSize变量(或任何你想要调用它们)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
