mysql - 选择特定年份后出生的人

Question

I have a table of employees which includes a column birth_day as well as PRIMARY KEY of emp_ID (employee ID). There is also another table called Works_With with the employee emp_ID and total_sales by employee

What I want to do is to select the top 5 performing employees born after certain year, which is 1970.

How would I proceed..

I am thinking it was this but didn't work

SELECT total_sales
FROM works_with
WHERE employee.birth_day => '1970/MM/DD' LIMIT 5 DESC;

Any suggestions?

Answer 1

If your birth_day column holds a datetime, this should work:

SELECT employee.emp_ID, total_sales
FROM works_with
INNER JOIN employee
ON works_with.emp_ID = employee.emp_id
       AND year(employee.birth_day) >= 1970 
ORDER BY total_sales DESC
LIMIT 5;
