How to Create a Table in MySQL: Syntax and Best Practices

Tables are where your data actually lives. A well-designed CREATE TABLE statement defines each column's type and rules, so bad data never enters your analytics pipeline in the first place.

Key Points

• Define columns with name + data type: customer_name VARCHAR(100)
• Add a PRIMARY KEY, usually id INT AUTO_INCREMENT
• Use NOT NULL for mandatory fields and DEFAULT for automatic values
• Add FOREIGN KEY constraints to connect related tables
• Inspect any table's structure later with DESCRIBE table_name;
• Clone a structure quickly with CREATE TABLE new_t LIKE old_t;

Example: CREATE TABLE customers (id INT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(100) NOT NULL, city VARCHAR(50), created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP);
