Question

質問：

アメリカ合衆国の所在地外の部門ごとに最低給与の従業員をすべて雇用しているすべての従業員の姓名、給与および職務を表示します。 このクエリから社長と副会長を除外します。 （使用サブクエリ/参加）

私はきちんと

これは私が試したものでサブクエリを使用して適切にこれを構造化するかどうかはわからないよ：

SELECT last_name, salary, job_id 
FROM employees join locations 
USING(department_id) 
WHERE job_id <> ANY (SELECT * 
        FROM employees 
        WHERE job_id <> 'AD_PRES' OR job_id <> 'AD_VP') 
AND salary > 
        (SELECT MIN(salary) 
        FROM employees 
        WHERE country_id <> 'US'); 

適切にこれを構造化する方法上の任意のヘルプは高く評価され。ありがとうございました。

Answer 1

SELECT 
    last_name, salary, job_id 
FROM employees a 
INNER JOIN locations b ON a.department_id = b.department_id 
WHERE a.job_id NOT IN (
    SELECT job_id 
    FROM employees 
    WHERE 
     (job_id <> 'AD_PRES' OR job_id <> 'AD_VP') AND 
     salary > (
      SELECT MIN(salary) 
      FROM employees 
      WHERE country_id <> 'US' 
     ) 
); 

Works？

Answer 2

SELECT last_name, 
     salary, 
     job_id 
FROM (
    SELECT last_name, 
     salary, 
     job_id, 
     RANK() OVER (PARTITION BY e.department_id ORDER BY salary) AS rnk 
    FROM employees e 
     INNER JOIN 
     departments d 
     ON (d.department_id = e.department_id) 
     INNER JOIN 
     locations l 
     ON (d.location_id = l.location_id) 
    WHERE e.job_id NOT IN ('AD_PRES', 'AD_VP') 
    AND l.country_id <> 'US' 
) 
WHERE rnk > 1;

クエリ2 - 分析関数をを使用せず：

SELECT last_name, 
     salary, 
     job_id 
FROM employees e 
     INNER JOIN 
     departments d 
     ON (d.department_id = e.department_id) 
     INNER JOIN 
     locations l 
     ON (d.location_id = l.location_id) 
WHERE e.job_id NOT IN ('AD_PRES', 'AD_VP') 
AND l.country_id <> 'US' 
AND e.salary > ANY(SELECT salary 
         FROM employees ee 
         WHERE ee.department_id = e.department_id); 

又は

AND e.salary > (SELECT MIN(salary) 
        FROM employees ee 
        WHERE ee.department_id = e.department_id);
