MySQL database

Overall outline

First intimate contact with MySQL
Why study databases?

Data persistence
Use a complete management system for unified management and easy query

Related concepts of database

DB: database: the "warehouse" where data is stored. It holds a series of organized data.

DBMS

Database Management System. A database is a container created and operated by a DBMS
Common database management systems: MySQL, Oracle, DB2, SqlServer, etc.
SQL

Structure Query Language: a language specifically used to communicate with databases.
Advantages of SQL: ① easy to learn; ② It is not the exclusive language of a specific database vendor, and almost all DBMS} support SQL; ③ Although simple, it is actually a powerful language. Using its language elements flexibly, it can carry out unusually complex and advanced database operations.

The relationship between the above three:

Characteristics of database storage data

1. Put the data into the table, and then put the table into the library
2. There can be multiple tables in a database. Each table has a name to identify itself. Table names are unique.
3. Tables have some features that define how data is stored in tables, similar to the design of "classes" in java.
4. A table consists of columns, which we also call fields. All tables are composed of one or more columns, and each column is similar to the "attribute" in java.
5. The data in the table is stored in rows, and each row is similar to the "object" in java.

MySQL software

introduce
Mysql database is subordinate to MySQL lab, headquartered in Sweden and later acquired by oracle.
Advantages: ① low cost: open source code, generally free trial; ② Simple: easy to install and use; ③ High performance: fast execution.
install
DBMS can be divided into two categories: ① DBMS (Access) based on shared file system; ② Client server based DBMS (MySQL, Oracle, SqlServer).
The version can be divided into: community version (free) and enterprise version (charged).
Download under Windows Platform: http://dev.mysql.com/downloads/mysql
Complete installation and uninstallation steps: https://blog.csdn.net/Y_BlueBlack/article/details/81433401
Start and stop MySQL service
Method 1: right click this computer - Management - Service - start or stop MySQL service
Mode 2:

Start: net start mysql service name 
Stop: net stop mysql service name

Sign in
mysql–h host name–u user name–p password
 Example: mysql -h localhost -u root -proot

sign out
exit or ctrl+C

Introduction to common MySQL commands

get into mysql, On the command line, enter
mysql–uroot–p####  (Of which:####(indicates password)
Example: mysql -uroot -proot

see mysql Which databases are in the
show databases;

Create a new database
create database Database name;
Example: create database book;

Select a database
use Database name;
Example: use test;

Query data table
show tables;

View which data tables are in the specified database
show tables from Database name;
Example: show tables from mysql;

Query the current database
select database();

Create a new data table
create table math(
id int,
name varchar(20));

View table structure
desc Table name;
Example: desc math;

View all records in the table
select * from Table name;
Example: select * from math;

Insert record into table
insert into Table name(Column name list) values(List of values corresponding to the column);
Note: Insert varchar or date Type data should be enclosed in single quotation marks
 Example: insert into math (id,name) values(1,"ton");

Modify record
update Table name set Column 1 = Value of column 1, Column 2 = Value of column 2 where ..
Example: update math set name="wugang" where id=1;

Delete record
delete from Table name where ...
Example: delete from math where id=1;

Delete data table
drop table Table name;
Example: drop table math;

View MySQL server version

Log in to mysql Server
select version();

Not logged in to mysql Server
 stay cmd Command interface input: mysql --version

Syntax specification of MySQL

It is not case sensitive, but it is recommended that keywords be capitalized and table names and column names be lowercase
Use each sentence; Or \ g, preferably with a semicolon
Each command can be indented or wrapped as needed
Notes: ① single line notes: # note text; ② Single line note: - note text; ③ Multiline note: / * note text*/

Classification of SQL language

DQL (Data Query Language): Data Query Language, which is used to retrieve data in the database, mainly SELECT statements;
DML (Data Manipulation Language): data manipulation language, which is used to change the data in the database, mainly including INSERT, UPDATE and DELETE statements;
DDL (Data Definition Language): data definition language, which is used to CREATE, modify and delete libraries and tables. It mainly includes CREATE, DROP and ALTER statements;
DCL (Data Control Language): data control language, which is used to define user access rights and security levels. It mainly includes GRANT and REVOKE statements;
TCL (Transaction Control Language): transaction control language, which is used to maintain data consistency, including COMMIT, ROLLBACK and SAVEPOINT statements.
