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]);
}
