Question

I am a bit stuck with SQL queries.

User should be able to search Postcode, Company name or Location

I have the following tables:

company table

companyid |     name        | location
      1      Shop One           New York
      2      Shop Two           France

postcode_areas table

postcode | companyid
     BB1       1
     BB3       1
     BB1       2

So if user type in BB1, then it should show the result Shop One, and Shop Two.

If user type the name of company or location – it will just search from company table.

Answer 1

Maybe:

select distinct c.*
from company c
join postcode_areas p on p.company_id = c.company_id
where c.name like <input>
or c.location like <input>
or p.postcode like <input>
