Update query without using IN

Increase employees salary by 10%

update employee
set salary=salary+(salary*(10/100))
where emp_id in (Select emp_id from emp_details);

The above can be re-written as:

update employee t1
set salary=salary+(salary*(10/100))
where t1.emp_id = (Select emp_id from emp_details where emp_id=t1.emp_id);
