Question

我需要使用MySQL和PHP使用一个订单获取MySQL表值。我在下面提供我的表格。

db_cat：

id     cat_name   cat_id     order_no

1       aaa        10          1

2       ggg        10          30

3        fff       10           11


4      sss         10           12

5      ddd         10            5

这里我尝试使用查询按照order_no列值获取数据：

select * from db_cat where cat_id='10' order by order_no asc

但它给了我错误的订单数据，如（11,12,30,1,5），我应该得到这样的订单数据（1,5,11,12,30）。

我的order_no数据类型为varchar。

您可以按顺序使用强制转换
