MySQL 如何搜索”ñ”并避免包含”n”的记录？

如果您在搜索“ñ”时不想要包含“n”的所有记录，请使用以下语法-

select *from yourTableName where yourColumnName LIKE '%ñ%' COLLATE utf8_spanish_ci;

让我们首先创建一个表。以下是查询-

mysql> create table NotIncludenDemo
   -> (
   -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> ClientName varchar(20)
   -> );
Query OK, 0 rows affected (1.07 sec)

以下是使用插入命令在表中插入一些记录的查询-

mysql> insert into NotIncludenDemo(ClientName) values('John');
Query OK, 1 row affected (0.21 sec)

mysql> insert into NotIncludenDemo(ClientName) values('Johñ');
Query OK, 1 row affected (0.14 sec)

mysql> insert into NotIncludenDemo(ClientName) values('Johnñy');
Query OK, 1 row affected (0.18 sec)

以下是使用select语句从表中显示所有记录的查询-

mysql> select *from NotIncludenDemo;

这将产生以下输出-

+----+------------+
| Id | ClientName |
+----+------------+
| 1 | John |
| 2 | Johñ |
| 3 | Johnñy |
+----+------------+
3 rows in set (0.00 sec)

以下是搜索“ñ”的查询-

mysql> select *from NotIncludenDemo where ClientName LIKE '%ñ%' COLLATE utf8_spanish_ci;

将产生以下输出-

+----+------------+
| Id | ClientName |
+----+------------+
| 2 | Johñ |
| 3 | Johnñy |
+----+------------+
2 rows in set (0.60 sec)
