如何在MYSQL中运行此脚本？

Question

This is my script from Oracle but I have problems running it on MySQL.

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;

The error that I get when I run it on MySQL:

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 said:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'GROUP BY s.branch_no LIMIT 0, 50' at line 7

Answer 1

Try seperating the query into small subqueries.

In your case I would try:

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