mysql 简单的增删改查语句

增加记录:

注:null关键字与auto_increment限制条件相结合,可以为字段自动赋值;字段必须全,且一一对应;字符型用单引号;

1 mysql> insert into test values('sunshine_habit','hello_world_lyq@163.com'
2     -> ,1558888888,null);
输出:
3 Query OK, 1 row affected (0.10 sec)

增加记录,给指定字段赋值:

1 mysql> INSERT INTO SHOP (id,name,price,sort) VALUES(13,'sugar',22.00,'A');
2 Query OK, 1 row affected (0.08 sec)

 

 

查询记录:

1 mysql> select * from test where name='sunshine_habit';
2 输出:
3 +----------------+-------------------------+--------------+----+
4 | name           | email                   | phone_number | id |
5 +----------------+-------------------------+--------------+----+
6 | sunshine_habit | hello_world_lyq@163.com |   1558888888 |  1 |
7 +----------------+-------------------------+--------------+----+
8 1 row in set (0.00 sec)

 修改记录:

1 mysql> update test set name='Sam' where name='sunshine';
输出:
2 Query OK, 1 row affected (0.06 sec) 3 Rows matched: 1 Changed: 1 Warnings: 0
