Python MongoDB Create Collection

🎯 한 줄 통찰 (One-line insight)

A MongoDB collection maps conceptually to a SQL table, but exhibits the same lazy-creation behavior as the database itself — it isn't created until a document is actually inserted into it. [S1]

🧠 핵심 개념 (Core concepts)

  • Collection — MongoDB's equivalent of a SQL table. [S1]
  • mydb["collectionname"] — references (but doesn't yet create) a collection. [S1]
  • Lazy creation — the collection isn't created until a document is inserted. [S1]
  • mydb.list_collection_names() — lists all collections in a database, for existence checks. [S1]

📖 세부 내용 (Details)

  • Reference a collection: mycol = mydb["customers"]. [S1]
  • List collections: print(mydb.list_collection_names()). [S1]
  • Check specific collection: collist = mydb.list_collection_names(); if "customers" in collist: print("The collection exists."). [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — Insert Document 챕터에서 실제 문서를 삽입해야 컬렉션이 진짜로 생성된다. [S1]

💻 코드 패턴 (Code patterns)

Reference and check a collection (Python):

mycol = mydb["customers"]
collist = mydb.list_collection_names()
if "customers" in collist:
    print("The collection exists.")
