You can simply do this:
Say you have two tables - employee and phone
INNER JOIN
select employee.first_name, employee.last_name, phone.home_number from employee, phone where phone.employee_id = employee.employee_id;
OR
select employee.first_name, employee.last_name, phone.home_number from employee join phone on phone.employee_id = employee.employee_id;
LEFT JOIN
select employee.first_name, employee.last_name, phone.mobile_number from employee left join phone on phone.employee_id = employee.employee_id;
RIGHT JOIN
select phone.fax_number, employee.first_name, employee.last_name from phone right join employee on phone.employee_id = employee.employee_id;

What are HEAP tables in MySQL?
Heap is no longer the accepted term for these kinds of tables in MySQL but it is still supported for backwards compatibility. The new accepted term is Memory and as the name suggest, Memory tables store their data directly in memory. Memory tables are used primarily as temporary tables. When you delete a row from a memory table, you do not free up space in the server memory. Space is only freed once the table is deleted.
