如何在MYSQL中運行此腳本？

Question

這是我的Oracle腳本，但是在MySQL上運行時遇到問題。

SELECT s.branch_no, SUM(s.staff_salary)
from staff AS s

HAVING SUM(staff_salary) = (SELECT MAX(SUM(S2.staff_salary))
                            FROM staff AS S2
                            GROUP BY S2.BRANCH_NO)
                            GROUP BY s.branch_no;

我在MySQL上運行它時收到的錯誤：

SELECT s.branch_no, SUM(s.staff_salary)
from staff AS s

HAVING SUM(staff_salary) = (SELECT MAX(SUM(S2.staff_salary))
                            FROM staff AS S2
                            GROUP BY S2.branch_no)
                            GROUP BY s.branch_no
 LIMIT 0, 50 

MySQL說：

＃1064-您的SQL語法有誤； 檢查與您的MySQL服務器版本對應的手冊以獲取正確的語法，以在第7行的'GROUP BY s.branch_no LIMIT 0，50'附近使用

Answer 1

嘗試將查詢分成小的子查詢。

在您的情況下，我會嘗試：

SELECT *
FROM (
    SELECT SUM(staff_salary) sm , branch_no
    FROM staff 
    GROUP BY BRANCH_NO
) s
ORDER BY sm DESC LIMIT 1
