我正试图在ASP.NET Gridview中绕过自定义分页,但我读到的所有示例似乎都充满了我不需要的东西(例如Scott Gu)
有人能指出我正确的方向指向易于理解基础知识的教程吗?
EXAMPE:如果我有以下存储过程......
Alter Procedure dbo.GetReqeusts
@Category nvarchar(50)
As
Begin
Select dbo.[Name],
dbo.[ID]
From dbo.[Table]
Where dbo.[Category] = @Category
End
此示例返回200行,如何将此存储过程转换为有效的分页过程?

4guysfromrolla.com有一系列关于working with and displaying data的文章。有几个关于custom paging。
存储过程的关键是使用ROW_NUMBER()
函数来限制要返回的记录:
SELECT RowNum, [Name], [ID]
FROM
(SELECT [Name], [ID]
ROW_NUMBER() OVER(ORDER BY [ID]) as RowNum
FROM [Table] t
WHERE [Category] = @Category
) as DerivedTableName
WHERE RowNum BETWEEN @startRowIndex AND (@startRowIndex + @maximumRows) - 1
