//排序-根据实际情况修改,注意这里不要指定a.的别名，不然会造成PageList方法的错误找不到排序列
//sql.OrderBy("a.CreateTime Desc");
//sql.OrderBy("a.Id");
sql.OrderBy("CreateTime Desc");
sql.OrderBy("Id");
response = await repository.PageList(sql, t.obj.PageIndex, t.obj.PageSize);
不然会提示

返回时会异常

• Message：无法绑定由多个部分组成的标识符 "a.CreateTime"。
  无法绑定由多个部分组成的标识符 "a.Id"。
  用MSSQL追踪代码转换后执行的结果
  exec sp_executesql N'SELECT * FROM (SELECT ROW_NUMBER() OVER (ORDER BY a.CreateTime Desc
  , a.Id) peta_rn, peta_inner.* FROM (SELECT DISTINCT a.*
  FROM Sales_Order_Exchange a
  LEFT JOIN Sales_Order_Exchange_Detail b
  ON a.Id=b.OrderId
  WHERE (a.ShopId=''b6fa1418-82fb-4ad3-9445-2bdc1b667981'')
  AND (a.IsDel=0)
  ) peta_inner) peta_paged WHERE peta_rn > @0 AND peta_rn <= @1',N'@0 bigint,@1 bigint',@0=0,@1=10

上面报错a.CreateTime，因为是用Peta框架自动生成了别名peta_inner
