SQL语句错误

Question

打印仅在巡航范围超过1000公里的飞机上获得认证的员工姓名。

SELECT E.ename
FROM Employees E, Certified C, Aircraft A
WHERE C.aid = A.aid AND E.eid = C.eid
GROUP BY E.eid, E.ename
HAVING EVERY (A.cruisingrange > 1000)

Oracle缺乏对HAVING EVERY子句的支持会产生错误

ORA-00907: missing right parenthesis

如何解决？

Answer 1

而不是每一个，选择最小的一个，并检查它是否大于1000

SELECT E.ename
FROM Employees E
INNER JOIN Certified C ON  E.eid = C.eid
INNER JOIN Aircraft A ON C.aid = A.aid
GROUP BY E.ename
HAVING MIN(A.cruisingrange) > 1000

正如戈登所说，我忘了提及，我将你的连接语法从隐式（逗号分隔）修改为显式连接语法。尽量避免使用隐式连接语法，这会在处理两个以上的表时导致错误。
