Answer 1

I agree with Phil's comment above.

For you table you can use FIND_IN_SET function -

SELECT * FROM table WHERE FIND_IN_SET(3, product_cat_id);

Answer 2

If you add a leading and trailing comma to the field, then you can use a straightforward like expression to select the rows of interest.

SELECT * FROM table
WHERE CONCAT(',', product_cat_id, ',') LIKE '%,3,%'

Answer 3

我估计FIND_IN_SET函数将是你的朋友。

Answer 4

select id, productname
from table
where product_cat_id like '%,3,%'
or product_cat_id like '3,%'
or product_cat_id like '%,3'

Answer 5

If you don't consider changing the structure of the table... sight:

This is a lame query:

SELECT `id`,`productname` 
FROM `place_table_name_here` 
WHERE `poduct_cat_id` LIKE '%3%';

but it will give you the answer.
