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 .

Example 01

Select * from

TableA A

join TableB B on A.columna=B.columnb

join TableC C on B.columnd=C.columnc;

Example02

Select * from employees e

Join department d on e.department_id=d.department_id

Join location l on d.location_id=l.location_id;
