[S1] ## 🧠 핵심 개념 (Core concepts) - **`mysql.connector.connect()`** — opens a connection given host/user/password (and optionally database). [S1] - **`mydb.cursor()`** — creates a cursor object used to execute SQL statements. [S1] - **`mycursor.execute(sql)`** — runs a raw SQL statement, e.g. `"CREATE DATABASE mydatabase"`. [S1] - **Checking existence** — `execute("SHOW DATABASES")` then iterate the cursor to list all databases. [S1] - **Connect directly to a database** — pass `database="mydatabase"` to `connect()`; errors if it doesn't exist. [S1] ## 📖 세부 내용 (Details) - Create a database: `mycursor.execute("CREATE DATABASE mydatabase")`. [S1] - List databases: `mycursor.execute("SHOW DATABASES"); for x in mycursor: print(x)`. [S1] - Connect to a specific database: `mysql.connector.connect(host=..., user=..., password=..., database="mydatabase")`. [S1] ## ⚖️ 모순 및 업데이트 (Contradictions & updates) 소스에서 모순되는 정보는 발견되지 않음. ## 🛠️ 적용 사례 (Applied in summary) 현재 발견된 실제 적용 사례가 없습니다 — 이 챕터에서 정의한 connect/cursor/execute 패턴이 이후 모든 Python MySQL 챕터에서 반복 재사용된다. [S1] ## 💻 코드 패턴 (Code patterns) Create a database via mysql.connector (Python): ```python import mysql.connector mydb = mysql.connector.connect( host="localhost", user="yourusername", password="yourpassword" ) mycursor = mydb.cursor() mycursor.execute("CREATE DATABASE mydatabase") ``` ## ✅ 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 Table]], [[SQL Create DB]] - **참조 맥락:** Python에서 MySQL을 다루는 connect/cursor/execute 패턴의 진입점. ## 📚 출처 (Sources) - [S1] W3Schools — Python MySQL Create Database — https://www.w3schools.com/python/python_mysql_create_db.asp ## 📝 변경 이력 (Change history) - 2026-07-04: Initial draft synthesized from the W3Schools "Python MySQL Create Database" page (Astra wiki-curation, P-Reinforce v3.1 format).
