如何制定这个SQL查询？

Question

我想要得到的employee numbers和start dates所有的员工具有start dates相等的最早日期.

我知道这是错的.但只是写作来展示我想要的东西.

SELECT     start_date, employee_no
FROM         [employees]
WHERE     (start_date = MIN(start_date))

Answer 1

你很亲密!

SELECT     start_date, employee_no
FROM         [employees]
WHERE     start_date = (SELECT MIN(start_date) FROM employees)
