SQL Drop DB

🎯 한 줄 통찰 (One-line insight)

DROP DATABASE permanently deletes a database and every table, view, procedure, and row inside it — an irreversible, admin-only operation. [S1]

🧠 핵심 개념 (Core concepts)

  • DROP DATABASE statement — permanently deletes an existing SQL database, including all its content (tables, views, stored procedures, data). [S1]
  • Requires admin privileges — dropping a database needs administrative access. [S1]
  • SyntaxDROP DATABASE databasename;. [S1]

🧩 추출된 패턴 (Extracted patterns)

  • Irreversibility warning — the source explicitly warns to "be careful" since everything in the database is destroyed at once — implying a backup (see SQL Backup DB) should precede this in practice. [S1]

📖 세부 내용 (Details)

  • Drop a database: DROP DATABASE testDB;. [S1]
  • Verify removal: SHOW DATABASES; (MySQL) or SELECT name FROM sys.databases; (SQL Server). [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 되돌릴 수 없는 명령이므로 실행 전 BACKUP DATABASE를 선행하는 것이 안전한 관행이다. [S1]

💻 코드 패턴 (Code patterns)

Drop a database (SQL):

DROP DATABASE testDB;
