below code display details of employees have been hired after employee 'jack' hired
all of information in single table.
my query:
select e.employee_name, e.hiredate employees e e.employee_hiredate > jack.hiredate;
to 'jack' table, need join:
select e.employee_name, e.hiredate employees e join employees jack on jack.employee_name = 'jack' e.employee_hiredate > jack.hiredate;
alternatively can use subquery:
select e.employee_name, e.hiredate employees e e.employee_hiredate > (select hiredate employees employee_name = 'jack');
