仅获取Group By返回的最高值

Question

这是我的表格（简化）的样子

agentID|amount
   1   |   5  
   2   |   2  
   3   |   4  
   3   |   2  
   1   |   3

现在，如果我这样做

SELECT agentID, SUM(amount) AS totalAmount FROM myTable GROUP BY agentID

我会得到每个agentID的金额总和。但是如果我只对返回的具有最大金额（金额）的agentID感兴趣呢？

尝试了类似

的内容

SELECT agentID, MAX(SUM(amount) AS Bought) FROM myTable GROUP BY agentID

OR

SELECT MAX(SELECT agentID, SUM(amount) AS Bought FROM myTable GROUP BY agentID) FROM myTable

但它返回语法错误：p

你可以在最后添加 ORDER BY

SELECT agentID, SUM(amount) AS totalAmount FROM myTable GROUP BY agentID ORDER BY SUM(amount) DESC LIMIT 1;
