使用存储过程进行分页

我正在尝试添加分页存储过程的排序功能.

I am trying to add sorting feature of my pagination stored procedure.

我该怎么做，到目前为止我创建了这个.它工作正常，但是当传递 @sort 参数时，它不起作用.

How can I do this, so far I created this one. It works fine but when pass the @sort parameter, it didn't work.

ALTER PROCEDURE [dbo].[sp_Mk] @page INT, @size INT, @sort nvarchar(50) , @totalrow INT OUTPUT AS BEGIN DECLARE @offset INT DECLARE @newsize INT IF(@page=0) begin SET @offset = @page; SET @newsize = @size end ELSE begin SET @offset = @page+1; SET @newsize = @size-1 end -- SET NOCOUNT ON added to prevent extra result sets from SET NOCOUNT ON; WITH OrderedSet AS ( SELECT *, ROW_NUMBER() OVER (ORDER BY @sort DESC) AS 'Index' FROM [dbo].[Mk] ) SELECT * FROM OrderedSet WHERE [Index] BETWEEN @offset AND (@offset + @newsize) SET @totalrow = (SELECT COUNT(*) FROM [dbo].[Mk]) END

推荐答案

一种方法(可能不是最好的)是使用动态 SQL

One way (possibly not the best) to do it is to use dynamic SQL

CREATE PROCEDURE [sp_Mk] @page INT, @size INT, @sort nvarchar(50) , @totalrow INT OUTPUT AS BEGIN DECLARE @offset INT DECLARE @newsize INT DECLARE @sql NVARCHAR(MAX) IF(@page=0) BEGIN SET @offset = @page SET @newsize = @size END ELSE BEGIN SET @offset = @page*@size SET @newsize = @size-1 END SET NOCOUNT ON SET @sql = ' WITH OrderedSet AS ( SELECT *, ROW_NUMBER() OVER (ORDER BY ' + @sort + ') AS ''Index'' FROM [dbo].[Mk] ) SELECT * FROM OrderedSet WHERE [Index] BETWEEN ' + CONVERT(NVARCHAR(12), @offset) + ' AND ' + CONVERT(NVARCHAR(12), (@offset + @newsize)) EXECUTE (@sql) SET @totalrow = (SELECT COUNT(*) FROM [Mk]) END
