Hello, I was wondering if the following could be done with an advanced sql-statement in MySQL 3.23:
I have 5 tables with the following columns: id, name, phonenumber I need to check for duplicate phonenumbers in the 5 tables, that is if the same phonenumber exists in 3 tables or more. I've tried with a JOIN and a COUNT, but it doesn't seem to work.
