MYSQL - How to get quotient in general enum?

Question

MySQL

Good afternoon!
There is a table:
| ID | CODE |
----------------
| 1 | 2.6 |
----------------
| 2 | 3, 6 |
----------------
| 3 | 3 |
I want to compose a SQL query in such a way as to display all the rows in which one way or another there are 3ka. Ie ID 2 and 3.
The number of CODES elements (3,5,6,1,...) can be arbitrarily large and the number of lines too.
Is it possible?

Answer 1

select * from table
where id = 3
and codes like '%3%'

Answer 2
