mysql - 当我搜索“ñ”时为什么包含“n”？

Question

我有问题。当我有这段代码SELECT FIRST_NAME FROM CONTACT WHERE FIRST_NAME LIKE '%ñ%'时，为什么它会返回FIRST_NAME没有n的所有ñ。我只期待那些ñ的人。提前致谢。

Answer 1

SELECT FIRST_NAME 
FROM CONTACT 
WHERE FIRST_NAME LIKE '%ñ%' COLLATE utf8_spanish_ci

尝试使用BINARY运算符以二进制方式比较字符串 -

SELECT FIRST_NAME FROM CONTACT WHERE FIRST_NAME LIKE BINARY '%ñ%'
