嗨，有人可以帮我修复此查询吗？错误写在下面。

列出至少两张票的乘客姓名，每张票价超过180英镑。

SELECT Name 
FROM Passenger 
WHERE Pid IN (SELECT p FROM (SELECT Pid AS p,count(*) AS c FROM Ticket
GROUP BY PID HAVING count(*) >1) AS tic);

错误：缺少右括号第4行

Answer 1

您的查询应该只是

SELECT name
FROM   passenger
WHERE  pid IN (SELECT pid
               FROM  Ticket
               GROUP  BY pid
               HAVING Count(*) > 1);
