ou can join as many tables as you want, and they can be joined as a mix of INNER and OUTER joins. Just keep chaining the JOINs together with ON clauses that match .
Select * from
join TableB B on A.columna=B.columnb
join TableC C on B.columnd=C.columnc;
Select * from employees e
Join department d on e.department_id=d.department_id
Join location l on d.location_id=l.location_id;
