Question

this is the first time I’m dabbling in Databases and was wondering if it was possible to do the following:
I have two tables

student (id, name, phone)
photos  (id, student_id, photo)

I wanted to retrieve the student phone who’s name is say ‘Tom’ but only if he has a photo.
Is it possible at all to have a condition like this?

Many thanks

Answer 1

select s.phone from student s 
inner join photos p 
on p.student_id=s.id
where p.photo is not null
