There is no TOAD specific SQL for inner-joins.  It works in whatever SQL environment you are in.

SELECT e.lname, d.name
   FROM employee e, department d
 WHERE e.dept_id = d.dept_id;

This is a normal join (which is also known as an INNER-JOIN).

If you wanted an OUTER-JOIN where one column in one table doesn't match the same column in the opposite table, thus it shows all NULLs, then you need to add a (+) sign to the optional table be it employee or department

SELECT e.lname, d.name
   FROM employee e, department d
 WHERE e.dept_id = d.dept_id (+);
