MySQL Basic simple operation

Learn to install Docker , then use it. (/Funny Face)
Before want to learn Mysql (Windows configuration is really troublesome), learned to Docker be convenient, directly use to Docker create a service is not Mysql flattered. To create a container, take a look at the Nginx creation process of sharing 04.
First check the local mirror.

[[email protected] ~]# docker imagesREPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

There is no Mysql image, then I will first pull a Mysql mirror.
Search Mysql for the following image first.

Then pull the image to the local, of course, the first official image.

[[email protected] ~]# docker pull docker.io/mysqlUsing default tag: latestTrying to pull repository docker.io/library/mysql ...latest: Pulling from docker.io/library/mysql683abbb4ea60: Pull complete0550d17aeefa: Pull complete7e26605ddd77: Pull complete9882737bd15f: Pull complete999c06ab75f6: Pull completec71d695f9937: Pull completec38f847c1491: Pull complete5e0cb05a8fc3: Pull completec89e3e373fca: Pull completefa39a2c9922d: Pull completeb293d9c897c4: Pull complete3dc061869740: Pull completeDigest: sha256:43ed4f8c9d1695e97a39cdfe9475af9096e3723cfb79d820d8da00d61a277a85Status: Downloaded newer image for docker.io/mysql:latest

Pull succeeds, now start creating the Mysql container.

[[email protected] ~]# docker run -itd --name=mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=000000 docker.io/mysql30d60b852cf57c5f4e7df36846b10149387bb2b736cecb11f12a2d64a3bdbf43

into the container.

[[email protected] ~]# docker exec -it mysql /bin/bash[email protected]:/#

Connect to the database.

Connect to the database successfully!
Learn to view the database first.

mysql> show databases;+--------------------+| Database           |+--------------------+| information_schema || mysql              || performance_schema || sys                |+--------------------+4 rows in set (0.01 sec)

The database is then created.

mysql> create database gubeiqing;Query OK, 1 row affected (0.02 sec)mysql> show databases;+--------------------+| Database           |+--------------------+| gubeiqing          || information_schema || mysql              || performance_schema || sys                |+--------------------+5 rows in set (0.00 sec)

Then use the database I just created gubeiqing .

mysql> use gubeiqing;Database changed

After entering this database, take a look at what tables are available.

mysql> show tables;Empty set (0.00 sec)

The data table is empty at this time, and then the data table is created.

mysql> create table gubeiqing1(name varchar(20) not null , age varchar(20) not null);Query OK, 0 rows affected (0.08 sec)

The general statement syntax for building a table is: CREATE TABLE table_name (column_name column_type); .
Now let's look at what the data table looks like.

mysql> desc gubeiqing1;+-------+-------------+------+-----+---------+-------+| Field | Type        | Null | Key | Default | Extra |+-------+-------------+------+-----+---------+-------+| name  | varchar(20) | NO   |     | NULL    |       || age   | varchar(20) | NO   |     | NULL    |       |+-------+-------------+------+-----+---------+-------+2 rows in set (0.00 sec)

You can see gubeiqing1 that the data table now has two columns. But there is no data, so now add the data to the table.

mysql> insert into gubeiqing1 (name,age) values ('gbq',21);Query OK, 1 row affected (0.04 sec)

If the data you are adding is a character type, you must use either single or double quotation marks.
Now look at all the contents of this table.

We can see that the data has been added by us.

mysql> select * from gubeiqing1;+------+-----+| name | age |+------+-----+| gbq  | 21  |+------+-----+1 row in set (0.00 sec)

The simple syntax for query statements is: SELECT column_name,column_name FROM table_name .

Insert a few more (you can insert without specifying the column name, but you need to know the order in which you inserted the data).

mysql> insert into gubeiqing1 values ('zhangsan',20);Query OK, 1 row affected (0.05 sec)mysql> insert into gubeiqing1 values ('lisi',19);Query OK, 1 row affected (0.03 sec)

Take a look.

mysql> select * from gubeiqing1;+----------+-----+| name     | age |+----------+-----+| gbq      | 21  || zhangsan | 20  || lisi     | 19  |+----------+-----+3 rows in set (0.00 sec)

Then learn to change the data.
Now I will lisi age change the field from 19 the 22 .

mysql> update gubeiqing1 set age=22 where name='lisi';Query OK, 1 row affected (0.04 sec)Rows matched: 1  Changed: 1  Warnings: 0

The basic simple syntax for changing data is: UPDATE table_name SET column_name1=values1,column_name2=values2 [WHERE 条件表达式] .

Check the data sheet again.

mysql> select * from gubeiqing1;+----------+-----+| name     | age |+----------+-----+| gbq      | 21  || zhangsan | 20  || lisi     | 22  |+----------+-----+3 rows in set (0.00 sec)

The fields you can see lisi age have been changed.
Database basic additions and deletions to check, has seen three, and then look at the deletion.
zhangsanremove this data from the data table.

mysql> delete from gubeiqing1 where name='zhangsan';Query OK, 1 row affected (0.39 sec)mysql> select * from gubeiqing1;+------+-----+| name | age |+------+-----+| gbq  | 21  || lisi | 22  |+------+-----+2 rows in set (0.00 sec)

Then delete the table, and finally delete the library.

mysql> drop table gubeiqing1;Query OK, 0 rows affected (0.13 sec)mysql> show tables;Empty set (0.00 sec)mysql> drop database gubeiqing;Query OK, 0 rows affected (0.09 sec)mysql> show databases;+--------------------+| Database           |+--------------------+| information_schema || mysql              || performance_schema || sys                |+--------------------+4 rows in set (0.00 sec)
