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；

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

增加记录，给指定字段赋值：

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

查询记录：

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

修改记录：

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