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.")
