Python MySQL Create Table

🎯 한 줄 통찰 (One-line insight)

INT AUTO_INCREMENT PRIMARY KEY is the standard way to add a self-incrementing unique ID column, and it can be applied either at table creation or retrofitted onto an existing table via ALTER TABLE ... ADD COLUMN. [S1]

🧠 핵심 개념 (Core concepts)

• CREATE TABLE — executed via mycursor.execute("CREATE TABLE ..."); the connection must specify the target database. [S1]
• SHOW TABLES — checks existing tables, same iteration pattern as SHOW DATABASES. [S1]
• INT AUTO_INCREMENT PRIMARY KEY — auto-generates a unique, incrementing ID starting at 1. [S1]
• Adding a primary key to an existing table — ALTER TABLE customers ADD COLUMN id INT AUTO_INCREMENT PRIMARY KEY. [S1]

📖 세부 내용 (Details)

• Create table: mycursor.execute("CREATE TABLE customers (name VARCHAR(255), address VARCHAR(255))"). [S1]
• With primary key: mycursor.execute("CREATE TABLE customers (id INT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(255), address VARCHAR(255))"). [S1]
• Add PK after the fact: mycursor.execute("ALTER TABLE customers ADD COLUMN id INT AUTO_INCREMENT PRIMARY KEY"). [S1]

💻 코드 패턴 (Code patterns)

Create table with auto-increment primary key (Python):

mycursor.execute(
    "CREATE TABLE customers (id INT AUTO_INCREMENT PRIMARY KEY, "
    "name VARCHAR(255), address VARCHAR(255))"
)
