How do I create databases and tables?

# Basic Schema Creation Connect to MySQL shell. ```sql CREATE DATABASE pets; 77 USE pets; CREATE TABLE cats ( id INT UNSIGNED NOT NULL AUTO_INCREMENT, name VARCHAR(150) NOT NULL, owner VARCHAR(150) NOT NULL, birth DATE NOT NULL, PRIMARY KEY (id) ); SHOW TABLES; DESCRIBE cats; ``` Practice in Workbench for visual table designer.

How do I manipulate data (crud)?

# Insert, Update, Delete ```sql INSERT INTO cats (name, owner, birth) VALUES ('Sandy', 'Lennon', '2015-01-03'), ('Cookie', 'Casey', '2013-11-13'); SELECT * FROM cats; UPDATE cats SET birth = '2016-05-21' WHERE name = 'Sandy'; DELETE FROM cats WHERE name = 'Cookie'; ``` Commit changes implicitly in MySQL (autocommit on). Practice multiple inserts.

How do I query data effectively?

# SELECT Mastery ```sql SELECT * FROM cats; SELECT name FROM cats WHERE owner = 'Casey'; -- Aggregate SELECT COUNT(*) FROM cats; -- Multiple tables (add dogs table first) CREATE TABLE dogs (...); SELECT c.name, d.name FROM cats c JOIN dogs d ON ...; ``` Explore GROUP BY, ORDER BY, LIMIT from [official tutorial](https://dev.mysql.com/doc/refman/8.4/en/tutorial.html). 75

How do I build a project and secure?

# Sample Project: Personal Library DB 1. Create DB `library`. 2. Tables: `books (id, title, author, isbn)`, `users (id, name)`. 3. Insert sample data. 4. Queries: Find books by author, count per user. ```sql ALTER TABLE books ADD INDEX idx_author (author); -- Secure: Create user CREATE USER 'appuser'@'localhost' IDENTIFIED BY 'password'; GRANT SELECT, INSERT ON library.* TO 'appuser'@'localhost'; ``` Backup: `mysqldump -u root -p library > backup.sql`.
