同时搜索2个字段以从MySQL的表中获取特定的名字和姓氏
为此，可以将LIKE运算符与AND一起使用。让我们首先创建一个表-
mysql> create table DemoTable ( EmployeeFirstName varchar(50), EmployeeLastName varchar(50) );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('John','Smith');
mysql> insert into DemoTable values('David','Miller');
mysql> insert into DemoTable values('John','Doe');
mysql> insert into DemoTable values('Adam','Smith');
mysql> insert into DemoTable values('Carol','Taylor');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-
+-------------------+------------------+ | EmployeeFirstName | EmployeeLastName | +-------------------+------------------+ | John | Smith | | David | Miller | | John | Doe | | Adam | Smith | | Carol | Taylor | +-------------------+------------------+ 5 rows in set (0.00 sec)
以下是查询以同时搜索2个字段，以FirstName以“Joh”开头和LastName以“Sm”开头的记录-
mysql> select *from DemoTable where EmployeeFirstName LIKE 'Joh%' and EmployeeLastName LIKE 'Sm%';
这将产生以下输出-
+-------------------+------------------+ | EmployeeFirstName | EmployeeLastName | +-------------------+------------------+ | John | Smith | +-------------------+------------------+ 1 row in set (0.00 sec)
