2024-04-22 05:49:03 350

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)
