SELECT tblusers.id, tblusers.user from tblusers, tblexperiences WHERE tblexperiences.id = tblusers.id

If I do this first SELECT it will return me a lot of duplicate rows, but I just need one time how can I do it?

And in another SELECT I have to get all users on tblexperiences WHERE has more than one row tblexperiences.id_users

Answer 1

SELECT tblusers.id, tblusers.user 
from tblusers
join tblexperiences ON tblexperiences.id = tblusers.id
group by tblusers.id, tblusers.user 

and for the second part of the question, add a

having count(tblexperiences.id) > 1
