Question

我正在尝试查询我的数据库，仅显示已收到至少60％订购手机的记录。

这是我的表的精简版：

dealID | Ordered | Received | precreditEL    | cancelled  | precredit
1      | 5       | 4        |                |            |
2      | 2       | 2        |                |            |
3      | 10      | 2        |                |            |
4      | 8       | 8        | Non-applicable |            |
5      | 6       | 5        | Non-applicable | Cancelled  | Ready

这是我当前的查询

select deals.dealID,customer_info.accName,account_info.accessid,account_info.access_password,customer_info.contactNumber,deals.est_bill,deals.precreditAssigned,deals.precreditEL,deals.precredit
from customer_info join deals
left join account_info  on account_info.custID = customer_info.custID
left join phone_details on phone_details.dealID = deals.dealID 
where customer_info.custID = deals.custID
and deals.precreditEL <> 'Non-applicable'
and deals.precredit <> 'Complete'
and deals.cancelled IS NULL
GROUP BY deals.dealID
having ((100 - (((sum(phone_details.ordered) - sum(phone_details.received)) / sum(phone_details.ordered)) * 100)) >= 60)

这完美无缺。只要precreditEL不是非适用且未标记为已取消，查询将为我提供已收到订单的60％的记录。所以我的结果将是dealID 1 and 2。

但现在我需要添加绕过这种情况的另一个条件。如果precredit被标记为Ready，则无论上述情况如何，结果都会显示记录。所以我的结果会显示dealID 1, 2 and 5

任何帮助将不胜感激。非常感谢你。

没关系，我通过改变

得到了它

having ((100 - (((sum(phone_details.ordered) - sum(phone_details.received)) / sum(phone_details.ordered)) * 100)) >= 60)

到

having (((100 - (((sum(phone_details.ordered) - sum(phone_details.received)) / sum(phone_details.ordered)) * 100)) >= 60) OR deals.precredit ='Ready')

用两个条件查询mysql
