Don't SHOUT! It's considered rude

Please do not use all CAPS. It is considered shouting and rude.

You cannot join them if there is nothing to join on otherwise you get a cross join. What output do you want?

Solution 1

You would not want to join two tables that have nothing in common.
What you can still do is a CROSS-JOIN that will list out all combination of rows - CROSS-JOIN[^].

Solution 2

Employees surely have to belong to some departments else they are employees. So add a column "deptno" in the "emp" table and link it to the "deptno" in the "dept" table, and now you have the relationship.
