ขอฮิสโตแกรมให้ฉันหน่อยว่ารหัสพนักงานทั้งหมดและชื่อประเทศที่พวกเขาทำงานคืออะไร เรียงตามแกน y จากสูงไปต่ำ ไม่จำเป็นต้องใช้ตารางทั้งหมด
Give me a histogram for what are all the employee ids and the names of the countries in which they work?, order by the y axis from high to low.It is not neccessary to use all the tables.
 locations:  LOCATION_ID [ decimal(40)]  STREET_ADDRESS [ varchar(40)]  POSTAL_CODE [ varchar(12)]  CITY [ varchar(30)]  STATE_PROVINCE [ varchar(25)]  COUNTRY_ID [ varchar(2)] 
SELECT COUNTRY_NAME, SUM(EMPLOYEE_ID) FROM employees AS T1 JOIN departments AS T2 ON T1.DEPARTMENT_ID = T2.DEPARTMENT_ID JOIN locations AS T3 ON T2.LOCATION_ID = T3.LOCATION_ID JOIN countries AS T4 ON T3.COUNTRY_ID = T4.COUNTRY_ID GROUP BY COUNTRY_NAME ORDER BY SUM(EMPLOYEE_ID) DESC
