您能否更改此查询,以便在使用WHERE子句时返回表中的所有记录,以便在需要时可以搜索特定记录。目前它没有返回任何内容:
select *, sum(price+shipping+paypalfee+storefee) as totalcost
from tblsales
group by orderno
where " . $where . "
order by $sort $order
limit $offset,$rows
答案 0 :(得分:0)
试试这个
select *,sum(totalcost)
FROM (select *, price+shipping+paypalfee+storefee as totalcost from tblsales) x
group by orderno
where " . $where . "
order by $sort $order
limit $offset,$rows
