SQLServer数据库分页查询

出表A中的第31条到40条记录（表A以自动增长的ID做主键，注意ID可能是不连续的

--事先删除了ID 为33的数据

 

--第一种

select top 10 ID from T where ID not in(select top 30 ID from T ORDER BY ID ASC)ORDER BY ID

 例：select top (@pageSize) * from table where id not in (select top ((@pageIndex-1)*@pageSize) id from table order by id ) order by id 

--第二种

SELECT * FROM (select top 10 * FROM( select top 40 * from T order by ID asc)TT order by TT.ID DESC)TTT order by TTT.ID asc

--第三种

select * from T where T.ID in( select top 10 ID FROM(select top 40 ID from T order by T.ID asc)TT order by TT.ID desc) order by ID

--第四种

select * from( select ROW_NUMBER() over(order by ID)TT FROM T)TTT WHERE TTT.TT between 30 and 40

 

 

分页存储过程的写法：

create Proc P_LoadPageData

 　--参数

　　@pageSize int,

　　@pageInderx int,

　　@total int out

as

　　--代码

　　select top (@pageSize) * from table where id not in

　　 (

　　　　select top ((@pageIndex-1)*@pageSize) id from table order by id

　 　)  order by id 

 

　　select total = count('a') from table

　　select total

 

--测试存储过程 

　　declare @total int

　　exec P_LoadPageData 3,5,@total out

　　print @total

　　select @total

 

//以下是在.net中调中存储过程

 

public System.Collections.Generic.List<Model.HKSJ_Main> LoadPageData(int pageIndex, int pageSize, out int total)
{
DataSet ds = new DataSet();

SqlParameter totalParameter = new SqlParameter("@total", SqlDbType.Int);
totalParameter.Direction = ParameterDirection.Output;
//DbHelperSQL.RunProcedure()

//如果用了输出参数，那么就用SqlDataAdapter就可以了，用sqlDataReader时候拿不到输出参数的值。
using (SqlConnection conn = new SqlConnection(DbHelperSQL.connectionString))
{
//conn.Open();
using (SqlDataAdapter adapter = new SqlDataAdapter("P_LoadPageData", conn))
{
adapter.SelectCommand.Parameters.Add(new SqlParameter("@pageIndex", pageIndex));
adapter.SelectCommand.Parameters.Add(new SqlParameter("@pageSize", pageSize));

adapter.SelectCommand.CommandType = CommandType.StoredProcedure;

//输出参数的用法
adapter.SelectCommand.Parameters.Add(totalParameter);

adapter.Fill(ds);
}
}
total = (int)totalParameter.Value;//拿到输出参数的值

return this.DataTableToList(ds.Tables[0]);

}
