如何使用PHP和MySQL对表值进行排序？

Question

I need to fetch MySQL table value using one order using MySQL and PHP. I am providing my table below.

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

Here I am trying to fetch data as per order_no column value by using the query :

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

but it is giving me the wrong order data like(11,12,30,1,5) where I should get the data like this order( 1,5,11,12,30 ).

my order_no datatype is varchar .

Answer 1

您可以按以下顺序使用演员表：

select * from db_cat where cat_id='10' order by cast(order_no as int) asc
