如何在MySQL中查询soundex()？

SOUNDEX()返回一个soundex字符串。两个听起来相似的字符串应该有相同的soundex字符串。

要在MySQL中查询soundex()，您可以使用以下语法 −

select *from yourTableName where soundex(yourValue)=soundex(yourColumnName);

让我们首先创建一个表 −

mysql> create table DemoTable
   (
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   FirstName varchar(20),
   LastName varchar(20)
   );
Query OK, 0 rows affected (0.28 sec)

使用insert命令将一些记录插入表中−

mysql> insert into DemoTable(FirstName,LastName) values('Adam','Smith');
Query OK, 1 row affected (0.04 sec)

mysql> insert into DemoTable(FirstName,LastName) values('David','Miller');
Query OK, 1 row affected (0.07 sec)

mysql> insert into DemoTable(FirstName,LastName) values('Carol','Taylor');
Query OK, 1 row affected (0.06 sec)

mysql> insert into DemoTable(FirstName,LastName) values('Chris','Brown');
Query OK, 1 row affected (0.06 sec)

mysql> insert into DemoTable(FirstName,LastName) values('John','Smith');
Query OK, 1 row affected (0.07 sec)

使用select语句显示表中的所有记录

mysql> select *from DemoTable;

这将产生以下输出−

+----+-----------+----------+
| Id | FirstName | LastName |
+----+-----------+----------+
| 1  | Adam      | Smith    |
| 2  | David     | Miller   |
| 3  | Carol     | Taylor   |
| 4  | Chris     | Brown    |
| 5  | John      | Smith    |
+----+-----------+----------+
5 rows in set (0.00 sec)

以下是MySQL中soundex()的查询。

mysql> select *from DemoTable where soundex('Smith')=soundex(LastName);

这将产生以下输出−

+----+-----------+----------+
| Id | FirstName | LastName |
+----+-----------+----------+
| 1  | Adam      | Smith    |
| 5  | John      | Smith    |
+----+-----------+----------+
2 rows in set (0.00 sec)
