Question

我正在我们的客户订单数据库上运行查询，以查看上周的销售情况。查询如下所示：

select
distinct day(from_unixtime(customerorder.datetime)) as day,
count(distinct customerorder.customerorderid) as count_totalorders,
count(distinct customerorderpos.itemid) as count_differentitems,
sum(customerorderpos.quantity_ordered) as quantity_ordered,
sum(customerorderpos.itemsubtotal) as item_subtotal,
sum(customerorderpos.pricechangetotal) as item_pricechangetotal,
sum(customerorderpos.itemtotal) as item_total,
sum(customerorderpos.purchase_price * customerorderpos.quantity_ordered) as item_purchasepricetotal,
sum(distinct cart_discounttotal) as total_discount,
sum(customerorderpos.itemtotal - (customerorderpos.purchase_price * customerorderpos.quantity_ordered) - (select distinct cart_discounttotal)) as item_earningstotal,
sum(distinct cart_total_shipping) as total_shipping,
sum(distinct cart_total_tax) as total_tax,
sum(distinct cart_total_complete) as total_complete
from customerorder
inner join customerorderpos on customerorder.customerorderid = customerorderpos.customerorderid
where
customerorder.datetime >= 1351494000 and
customerorder.status_cancelled = "0"
group by day(from_unixtime(customerorder.datetime))
order by customerorder.datetime

当我在PhpMyAdmin中输入查询时工作正常并显示最近7天的订单。但是当我们在自己的软件中运行它时会出错。

$result = $db->query($query);
while ($row = $result->fetch_assoc()){

这表明：“致命错误：在非对象上调用成员函数fetch_assoc（）”

但....如果我从查询中取出“where customerorder.datetime＆gt; = 1351494000”，它可以正常工作。换句话说，查询完美无缺，直到我想将其限制在特定时间。 Customerorder.datetime是一个带有时间戳的int（11）列。

任何想法可能是什么问题？

感谢您的帮助！

Answer 1

我认为这里的问题是在这一部分

      customerorder.datetime >= 1351494000

像这样：

      customerorder.datetime >= '1351494000'

您必须将其封闭才能使其正常工作。希望这有帮助。

Answer 2

感谢您的帮助。我发现了问题，但这当然是我自己的错误！实际的SQL语法很好，我只是在我们自己的软件中出错（$ query正在运行一个清理函数，取代了“＆gt; =”字符，使查询无效）。

抱歉浪费你的时间:(

php mysql查询错误与“where”
