not sure about the exact syntax, but to give you an idea:

select av.starttime as start_time,ap.starttime as end_time from availability av, appointments ap where av.emp_id=ap.emp_id and av.emp_id=1;

Same concept for the second row and then use the union-feature of the select-command to join.

hope this helps,
