此处第二个表中的税收列是一个月。我想获取去年缴纳最高税款的员工的姓名。这里第二个表中的员工 ID 引用了第一个表中的员工 ID。
最佳答案
使用此代码。
select salary.employeeid,firstname,lastname, sum(tax)
from salary
left join employee
on salary.employeeid=employee.employeeid
group by salary.employeeid,firstname,lastname
order by sum(tax) DESC LIMIT 1
关于sql - 如何根据另一张表中的最高纳税额获取一张表中的名称？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13835797/
