📌 What is a Table in MySQL?

A table in MySQL is a structured format to store data. Each table has:

  • Columns: Fields (like id, name, email)
  • Rows: Individual records of data
  • Constraints: Rules for data (like primary key, not null)

🧑‍💻 How to Create a Table (Using MySQL Workbench)

  1. Open MySQL Workbench
  2. Connect to your local MySQL server
  3. Expand your database/schema in the left pane
  4. Right-click on Tables > Create Table
  5. In the table editor, add:
    • id – INT – Primary Key – Auto Increment
    • name – VARCHAR(100)
    • email – VARCHAR(100)
    • created_at – DATETIME – Default: CURRENT_TIMESTAMP
  6. Click Apply, review SQL, and confirm

✔️ Your table is now created and ready for data entry.

✍️ How to Create a Table Using SQL

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100) NOT NULL,
    email VARCHAR(100) NOT NULL,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);

✅ Explanation:

  • id: Auto-incremented unique identifier
  • name: User’s full name, cannot be NULL
  • email: User’s email address, also required
  • created_at: Automatically stores the timestamp when the row is created

  • Always use a primary key
  • Use NOT NULL on mandatory fields
  • Set a default for created_at for audit purposes
  • Use consistent naming conventions

🙋‍♂️ Who Is This For?

  • Beginners learning SQL and database concepts
  • Students building academic projects
