我已经为许多表中的 100+ 百万条记录执行了与以下相同的功能，包括自定义分页（使用 storedProc），还更新、删除和插入：
CREATE PROCEDURE [dbo].[sp_Mk]
@PageIndex INT,
@PageSize INT,
@tableName nvarchar(255),
@totalRow INT Output
AS
BEGIN
DECLARE @sql NVARCHAR(MAX)
Declare @anotherSql NVARCHAR(1000)
DECLARE @ParamDefinition NVARCHAR(500)
--DECLARE @totalRow INT
Set @sql = 'WITH TempResult AS( SELECT * FROM '+@tableName+'), TempCount AS ( SELECT COUNT(*) AS MaxRows FROM TempResult )
SELECT * FROM TempResult, TempCount ORDER BY (Select Null)
OFFSET '+CONVERT(VARCHAR(20),(@PageIndex-1)*@PageSize) +' ROWS FETCH NEXT '+CONVERT(VARCHAR(20),@PageSize)+' ROWS ONLY'
PRINT @SQL
EXECUTE sp_executesql @SQL
Set @anotherSql=N'SELECT COUNT(*) as totalRow FROM '+@tableName
SET @ParamDefinition = N'@totalRowOutPut INT OUTPUT'
--PRINT @anotherSql
Execute sp_executesql @anotherSql,
@ParamDefinition,
--@tableNameInput=@tableName,
@totalRowOutPut=@totalRow OUTPUT
End
