MySQL之旅(2) 创建数据库 数据表 插入数据 MySQL可视化工具Navicat for MySQL

导言:若木有安装破解版Navicat for MySQL软甲,传送门已备好---> 传送门:安装破解版Navicat

第一步:可视化工具Navicat for MySQL连接MySQL

  1·启动MySQL 

    npm指令--切换目录:

cd C:\web\mysql-8.0.11\bin

    npm指令--初始化数据库:

mysqld --initialize --console

    执行完成后,会输出 root 用户的初始默认密码:

...
2018-04-20T02:35:05.464644Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: APWCY5ws&hjQ
...

    npm指令--安装 :

mysqld install

    npm指令--启动:

net start mysql

  2· 连接Navicat for MySQL

      

第二步:连接成功 创建数据库 右击Navicat左侧打开  命令列界面

  tips:因为我自己MySQL前一秒写数据了 并不影响 ;

  1· 创建数据库指令:

CREATE DATABASE 数据库名;

  2· 使用数据库(切记 每次完整的命令结尾用 ';'): 

use 数据库名;

  3·数据库创建表单(表格):

mysql> create table Fruits (
    -> id int(11),
    -> name VARCHAR(255),
    -> price DECIMAL(10,2),
    -> discount DECIMAL(10,2),
    -> manufacturer VARCHAR(255),
    -> shop VARCHAR(255),
    -> shopname VARCHAR(255),
    -> incorporation DATE,
    -> operationstatus tinyint(1),
    -> shopbox VARCHAR(255),
    -> address VARCHAR(255),
    -> onlinephone int(11)
    -> );

  tips: 每行指令前缀 -> 是Navicat自带分行 别搞错了, Query OK, 0 rows affected  表示创建成功!

  4·显示你所创建的表单 table :

show full columns from fruits;

  :显示结果

+-----------------+---------------+--------------------+------+-----+---------+-------+---------------------------------+---------+
| Field           | Type          | Collation          | Null | Key | Default | Extra | Privileges                      | Comment |
+-----------------+---------------+--------------------+------+-----+---------+-------+---------------------------------+---------+
| id              | int           | NULL               | YES  |     | NULL    |       | select,insert,update,references |         |
| name            | varchar(255)  | utf8mb4_0900_ai_ci | YES  |     | NULL    |       | select,insert,update,references |         |
| price           | decimal(10,2) | NULL               | YES  |     | NULL    |       | select,insert,update,references |         |
| discount        | decimal(10,2) | NULL               | YES  |     | NULL    |       | select,insert,update,references |         |
| manufacturer    | varchar(255)  | utf8mb4_0900_ai_ci | YES  |     | NULL    |       | select,insert,update,references |         |
| shop            | varchar(255)  | utf8mb4_0900_ai_ci | YES  |     | NULL    |       | select,insert,update,references |         |
| shopname        | varchar(255)  | utf8mb4_0900_ai_ci | YES  |     | NULL    |       | select,insert,update,references |         |
| incorporation   | date          | NULL               | YES  |     | NULL    |       | select,insert,update,references |         |
| operationstatus | tinyint(1)    | NULL               | YES  |     | NULL    |       | select,insert,update,references |         |
| shopbox         | varchar(255)  | utf8mb4_0900_ai_ci | YES  |     | NULL    |       | select,insert,update,references |         |
| address         | varchar(255)  | utf8mb4_0900_ai_ci | YES  |     | NULL    |       | select,insert,update,references |         |
| onlinephone     | int           | NULL               | YES  |     | NULL    |       | select,insert,update,references |         |
+-----------------+---------------+--------------------+------+-----+---------+-------+---------------------------------+---------+
12 rows in set

  5·给表单出入数据 可插入多条数据:

insert into tablename (...所要插入的参数) values (...所要插入的值)

  forexample:

insert into fruits (id,name,price,discount,manufacturer,shop,shopname,incorporation,operationstatus,shopbox,address,onlinephone)
    -> values ('15','iphone 8','1000.99','990.88','浙江义乌','义乌数码科技市场','iPhone体验店','2010-10-01','1','小丫丫','陕西西安雁塔','082088820'), ('16','iphone 8Plus','1070.99','919.88','浙江义乌','义乌数码科技市场','iPhone店','2010-10-01','1','小丫丫','陕西西安雁塔','082088820'),('17','ipone SE','1000.99','990.88','浙江义乌','义乌数码科技市场','iPhone店','2010-10-01','1','小丫丫','陕西西安雁塔','082088820'), ('18','iphone SE2','1070.99','919.88','浙江义乌','义乌数码科技市场','iPhone店','2010-10-01','1','小丫丫','陕西西安雁塔','082088820'),('19','iphone Max','1000.99','990.88','浙江义乌','义乌数码科技市场','iPhone店','2010-10-01','1','小丫丫','陕西西安雁塔','082088820'), ('20','vivo','1070.99','919.88','浙江义乌','义乌数码科技市场','iPhone店','2010-10-01','1','小丫丫','陕西西安雁塔','082088820'),('21','HUAWEI','1000.99','990.88','浙江义乌','义乌数码科技市场','华为体验店','2010-10-01','1','小丫丫','陕西西安雁塔','082088820'), ('22','vivo','1070.99','919.88','浙江义乌','义乌数码科技市场','vivo体验店','2010-10-01','1','小丫丫','陕西西安雁塔','082088820'),('23','HUAWEI','1000.99','990.88','浙江义乌','义乌数码科技市场','华为体验店','2010-10-01','1','小丫丫','陕西西安雁塔','082088820'), ('24','vivo','1070.99','919.88','浙江义乌','义乌数码科技市场','vivo体验店','2010-10-01','1','小丫丫','陕西西安雁塔','082088820');

  tips: 显示 

Query OK, 10 rows affected
Records: 10  Duplicates: 0  Warnings: 0

  表示数据成功;

 

end...
