MySQL查询对列中的特定姓氏进行基本搜索
您可以使用LIKE运算符对姓氏进行基本搜索。我们首先创建一个表：-
mysql> create table DemoTable -> ( -> CustomerName varchar(100), -> CustomerAge int -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('John Doe',34);
mysql> insert into DemoTable values('David Miller',24);
mysql> insert into DemoTable values('Bob Doe',27);
mysql> insert into DemoTable values('Carol Taylor',29);使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
输出结果
这将产生以下输出-
+--------------+-------------+ | CustomerName | CustomerAge | +--------------+-------------+ | John Doe | 34 | | David Miller | 24 | | Bob Doe | 27 | | Carol Taylor | 29 | +--------------+-------------+ 4 rows in set (0.00 sec)
以下是从列中搜索姓氏的查询-
mysql> select *from DemoTable where CustomerName LIKE '%Doe%';
输出结果
这将产生以下输出-
+--------------+-------------+ | CustomerName | CustomerAge | +--------------+-------------+ | John Doe | 34 | | Bob Doe | 27 | +--------------+-------------+ 2 rows in set (0.00 sec)
