使用分页存储过程
Create  PROCEDURE ListPage(

@page  int = 1,           ----要显示那一页的记录
@pageCount int = 1 output,          ----查询结果分页后的总页数
@Counts int = 1 output,           ----查询到的记录数
@fldSort nvarchar(100) = null,          ----排序字段列表或条件
@Sort  bit = 0,           ----排序方法,0为升序,1为降序
@strCondition nvarchar(200) = null, ----查询条件,不需where
@ID  nvarchar(50)  ----主表的主键

SET NOCOUNT ON
Declare @sqlTmp nvarchar(1000)  ----存放动态生成的SQL语句

------恢复系统设置-----
