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): ```python mycursor.execute( "CREATE TABLE customers (id INT AUTO_INCREMENT PRIMARY KEY, " "name VARCHAR(255), address VARCHAR(255))" ) ``` ## ✅ 검증 상태 및 신뢰도 - **상태:** draft - **검증 단계:** conceptual - **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body) - **신뢰 점수:** 0.88 - **중복 검사 결과:** 신규 생성 (New discovery) ## 🔗 지식 그래프 (Knowledge Graph) - **상위/루트:** [[Python Tutorial]] - **관련 개념:** [[Python MySQL Create Database]], [[Python MySQL Insert]], [[SQL Auto Increment]] - **참조 맥락:** MySQL 테이블 생성 및 기본키 설정 — 이후 Insert Into로 데이터가 채워진다. ## 📚 출처 (Sources) - [S1] W3Schools — Python MySQL Create Table — https://www.w3schools.com/python/python_mysql_create_table.asp ## 📝 변경 이력 (Change history) - 2026-07-04: Initial draft synthesized from the W3Schools "Python MySQL Create Table" page (Astra wiki-curation, P-Reinforce v3.1 format).
