Question

我必须打印不以元音开头和结尾的名字列表。我输入以下查询：

SELECT DISTINCT NAME 
FROM STUDENT 
WHERE NAME NOT LIKE '[AEIOU]%' 
  AND NAME NOT LIKE '%[aeiou]' 
ORDER BY NAME;

它在输出屏幕上没有产生任何结果。这有什么问题？

Answer 1

使用RLIKE和正则表达式：

SELECT DISTINCT NAME 
FROM STUDENT 
WHERE NAME RLIKE '^[^aeouiy].*[^aeouiy]$' 
ORDER BY NAME;
