使用MySQL IN()根据LastName提取记录
让我们首先创建一个表-
mysql> create table DemoTable ( FirstName varchar(100), LastName varchar(100) );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('Adam','Smith');
mysql> insert into DemoTable values('John','Doe');
mysql> insert into DemoTable values('John','Smith');
mysql> insert into DemoTable values('Chris','Brown');
mysql> insert into DemoTable values('Robert','Brown');
mysql> insert into DemoTable values('David','Miller');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-
+-----------+----------+ | FirstName | LastName | +-----------+----------+ | Adam | Smith | | John | Doe | | John | Smith | | Chris | Brown | | Robert | Brown | | David | Miller | +-----------+----------+ 6 rows in set (0.00 sec)
以下是使用MySQL根据LastName获取记录的查询IN()-
mysql> select *from DemoTable where LastName IN('Smith','Brown','Miller');这将产生以下输出-
+-----------+----------+ | FirstName | LastName | +-----------+----------+ | Adam | Smith | | John | Smith | | Chris | Brown | | Robert | Brown | | David | Miller | +-----------+----------+ 5 rows in set (0.00 sec)
