Hibernate Query 3嵌套选择

Question

如何修复当前工作的查询？

Query query = getSession().createQuery(
    "FROM Rates WHERE amount = 
        (SELECT MIN(amount) FROM
            (SELECT amount FROM Rates
            GROUP BY amount having COUNT(*) = 1))"); 

IntellijIDE编译器显示

')', ',', FETCH, GROUP, HAVING, IN, ORDER, WHERE or identifier expected, got '(

并在此FROM (SELECT

下划线红线(

如果我理解您的请求，您可以尝试：

"FROM Rates r1 WHERE r1.amount in 
    (SELECT MIN(r2.amount) FROM Rates r2
        GROUP BY r2.amount having COUNT(r2.amount) = 1))"

告诉我它是否正常
