Question

I have two tables property_description and property_extras.

Table property_description looks like

id location price etc etc
1  New York 3000   v    v

Table property_extras looks like

property_id  extras
1           12,14,16,167

Well the question is how should mysql query it look to return result only if at least one of extras is matched ?

Answer 1

You should ideally have extras normalized like

property_id  extra_id
1            12
1            14
...

If you can’t convert your database structure into something like this, then you have to do something (terrible) like:

SELECT property_id FROM property_extras WHERE
    extras LIKE '12,%' OR extras LIKE '%,12,%' OR  extras LIKE '%,12'

Or, If you can insert commas to the start and to the end like ,12,14,..., as delphist points out, simply:

SELECT property_id FROM property_extras WHERE extras LIKE '%,12,%'
