在 sql 中為兩個派生表使用 JOIN

Question

基本上，我有兩個單獨的查詢，我需要以某種方式將它們合並到一組結果中。

,[這是表1，顯示了每組工資的總和] 1

這是我為形成表格而編寫的查詢。

SELECT con_stagename, SUM(p_daily_salary) AS sum_salary
                FROM CONTENDER, PARTICIPANT
                WHERE p_contender = con_id
                GROUP BY con_id;
                
SELECT MAX(sum_salary) AS max_salary
FROM (SELECT con_stagename, SUM(p_daily_salary) AS sum_salary
                FROM CONTENDER, PARTICIPANT
                WHERE p_contender = con_id
                GROUP BY con_id) T2;

問題是，如果我希望結果是單行值，即薪水最高的組的名稱和實際金額。 我該怎么做？ 我一直在嘗試使用 JOIN 操作，但沒有運氣。

Answer 1

SELECT con_stagename, SUM(p_daily_salary) AS sum_salary
FROM CONTENDER, PARTICIPANT
WHERE p_contender = con_id
GROUP BY con_id
ORDER BY 2 DESC
LIMIT 1
