Sql Service中的分页

创建存储过程如下：

CREATE PROCEDURE [dbo].[sp_GetPageList]
    @TableName varchar(5000),        --表名
    @SelectFields varchar(5000) = '*',    --字段名(全部字段为*)
    @OrderField varchar(5000),        --排序字段(必须!支持多字段)
    @sqlWhere varchar(5000) = Null,--条件语句(不用加where)
    @pageSize int,                    --每页多少条记录
    @pageIndex int = 1 ,            --指定当前为第几页
    @totalRecord int = 0 OUTPUT,
    @TotalPage int output            --返回总页数
AS
BEGIN
    Begin Tran --开始事务
    Declare @sql nvarchar(4000); 
    print @totalRecord
    --if @totalRecord<=0 begin
        --计算总记录数
        if (@SqlWhere='' or @sqlWhere is NULL)
            set @sql = 'select @totalRecord = count(*) from ' + @TableName
        else
            set @sql = 'select @totalRecord = count(*) from ' + @TableName + '  where ' + @sqlWhere
            
        EXEC sp_executesql @sql,N'@totalRecord int OUTPUT',@totalRecord OUTPUT--计算总记录数       
    --end
    --计算总页数
    select @TotalPage=CEILING((@totalRecord+0.0)/@PageSize)
    if (@SqlWhere='' or @sqlWhere is NULL)
        set @sql = 'Select * FROM (select ROW_NUMBER() Over(order by ' + @OrderField + ') as rowId,' + @Fields + ' from ' + @TableName 
    else
        set @sql = 'Select * FROM (select ROW_NUMBER() Over(order by ' + @OrderField + ') as rowId,' + @Fields + ' from ' + @TableName + ' where ' + @SqlWhere    
    --处理页数超出范围情况
    if @PageIndex<=0 
        Set @pageIndex = 1
    if @pageIndex>@TotalPage
        Set @pageIndex = @TotalPage
     --处理开始点和结束点
    Declare @StartRecord int
    Declare @EndRecord int
    set @StartRecord = (@pageIndex-1)*@PageSize + 1
    set @EndRecord = @StartRecord + @pageSize - 1
    --继续合成sql语句
    set @Sql = @Sql + ') as t where rowId between ' + Convert(varchar(50),@StartRecord) + ' and ' +  Convert(varchar(50),@EndRecord)
        print @sql 
    Exec(@Sql)
    ---------------------------------------------------
    If @@Error <> 0
    Begin
        RollBack Tran
        Return -1
    End
    Else
    Begin
        Commit Tran
        Return @totalRecord ---返回记录总数
    End   
END
