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
