Question

从 STATION 查询不以元音开头或不以元音结尾的城市名称列表。您的结果不能包含重复项。

输入格式

STATION表描述如下：

我写了下面的查询，但工作正常。有什么建议吗？

SELECT DISTINCT city FROM station WHERE city NOT RLIKE '^[aeiouAEIOU].*[aeiouAEIOU]$';

Answer 1

这个 SQL 查询会对你有帮助。如果您使用的是 MS SQL，请按照下面给出的这行代码进行操作：

SELECT DISTINCT CITY 
FROM STATION  
WHERE CITY NOT LIKE '[AEIOU]%' OR CITY NOT LIKE '%[aeiou]';

如果您使用 MySQL，请按照下面给出的这行代码操作：

SELECT DISTINCT CITY 
FROM STATION 
WHERE (CITY NOT IN (SELECT DISTINCT CITY FROM STATION WHERE CITY LIKE '%a' OR CITY LIKE '%e' OR CITY LIKE '%i' OR CITY LIKE '%o' OR CITY LIKE '%u'))
OR 
(CITY NOT IN (SELECT CITY FROM STATION WHERE CITY LIKE 'A%' OR CITY LIKE 'E%' OR CITY LIKE 'I%' OR CITY LIKE 'O%' OR CITY LIKE 'U%'));

脚注：RLIKE和DISTINCT

Answer 3

SELECT DISTINCT city
FROM   station
WHERE  city REGEXP '^[^aeiouAEIOU]|[^aeiouAEIOU]$'

Answer 4

 SELECT DISTINCT city FROM station WHERE city RLIKE '^[^aeiouAEIOU].* 
 [^aeiouAEIOU]$';

您必须将插入字符放在方括号内，这意味着没有任何元音。这是解释
