Question

select si.total 
from sales_inv si,c nf_order co 
where si.order_num=co.order_no 
and co.cnf_no='CNF001' 
and co.added_on 
between '$month1' and '$month2'

在此查询中，我想从表sales_inv中获取销售发票中的order_num和order_number中的cnf_order应该相等的总数。

added_on是一个时间戳，应该在$month1和$month2之间

$month1和$month2是以时间戳格式存储数月的变量

这个查询不起作用，我做错了什么？

Answer 1

你试过这个吗？

select si.total 
from sales_inv si,c nf_order co 
where si.order_num=co.order_no 
and co.cnf_no='CNF001' 
and ( co.added_on 
between '$month1' and '$month2')

   select si.total 
    from sales_inv si,c nf_order co 
    where si.order_num=co.order_no 
    and co.cnf_no='CNF001' 
    and ( DATE(co.added_on) 
    between DATE('$month1') and DATE('$month2'))

Answer 2

尝试：

select si.total 
from sales_inv si,c nf_order co 
where si.order_num=co.order_no 
and co.cnf_no='CNF001' 
and co.added_on 
between STR_TO_DATE('$month1', '%Y-%m-%d') and STR_TO_DATE('$month2', '%Y-%m-%d')

查询之间的MySql日期出错了
