Procedures and views
This class is for those who want to learn mariadb and mysql DB. All classes are conducted with a focus on practice while also covering theory.
In the basics, you will learn mainly about DB installation, DDL syntax for table construction (CREATE, ALTER, DROP), DML syntax for processing data within tables (insert, select, update, delete), types, constraints, etc.
In the advanced section, you will learn about transactions, concurrency issue resolution, joins, indexes, DB design (ERD design, normalization), DB dump operations, procedures, and views.
Those who have basic knowledge of SQL queries can skip the basics and go to the advanced section. (You should know queries such as lookups and inserts and what pk and fk are. That should be enough.)
However, since the advanced course is conducted using the DB built in advance in the basic course, if you build the DB according to the procedure below, you will have no difficulty taking the advanced course right away.
1 ) Download and install mariadb, install workbench (or dbeaver, datagrip), install vscode
2 ) Board database creation query statement
CREATE DATABASE board; USE board;
3 ) Create author table and insert data
3 -1 ) Create a table
CREATE TABLE author (id INT NOT NULL AUTO_INCREMENT, name VARCHAR ( 100 ) DEFAULT 'anonymous' , email VARCHAR ( 255 ) NOT NULL , password VARCHAR ( 20 ), age TINYINT UNSIGNED, gender CHAR ( 1 ), self_introduction TEXT, profile_image VARCHAR ( 255 ), role ENUM( 'user' , 'admin' ) NOT NULL DEFAULT 'user' , PRIMARY KEY (id), UNIQUE (email));
3 -2 ) Data insertion
INSERT INTO author (name, email, password) VALUES ( 'hong1' , 'hong1@naver.com' , '1234' ), ( 'hong2' , 'hong2@naver.com' , '1234' ), ( 'hong3' , 'hong3@naver.com' , '1234' ), ( 'hong4' , 'hong4@naver.com' , '1234' ), ( 'hong4' , 'hong5@naver.com' , '1234' );
4 ) Create posts table and insert data
4 -1 ) Create a table
CREATE TABLE posts (id INT NOT NULL AUTO_INCREMENT, title VARCHAR ( 255 ) NOT NULL , contents VARCHAR ( 3000 ), author_id INT , price DECIMAL ( 10 , 3 ), created_time DATETIME DEFAULT CURRENT_TIMESTAMP (), user_id CHAR ( 36 ) DEFAULT UUID(), PRIMARY KEY (id), KEY (author_id), CONSTRAINT post_author_fk FOREIGN KEY (author_id) REFERENCES author (id) ON DELETE CASCADE);
4 -2 ) Insert data
INSERT INTO posts (title, contents, author_id, price) VALUES ( 'java' , 'java is ...' , 1 , null ),( 'python' , 'python is ...' , 1 , null ),( 'java2' , null , 1 , 10.346 );All class materials are based on the Notion materials in the link below.
