PHP MySQL Insert

🎯 한 줄 통찰 (One-line insight)

AUTO_INCREMENT and default-timestamp columns must be OMITTED from the INSERT statement entirely — the id and reg_date columns aren't listed in INSERT INTO MyGuests (firstname, lastname, email) at all, since MySQL fills them in automatically; explicitly specifying them would defeat their automatic behavior. [S1]

🧠 핵심 개념 (Core concepts)

  • INSERT INTO table (columns) VALUES (values) — adds a new record. [S1]
  • Quoting rules — the whole SQL query is quoted in PHP; string values inside are quoted; numeric values are NOT quoted; NULL is never quoted. [S1]
  • AUTO_INCREMENT/default-timestamp columns are omittedid and reg_date don't appear in the column list at all; MySQL fills them automatically. [S1]

📖 세부 내용 (Details)

  • Insert statement omitting auto-managed columns: $sql = "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('John', 'Doe', 'john@example.com')";. [S1]
  • MySQLi OOP execution: if ($conn->query($sql) === TRUE) { echo "New record created successfully"; } else { echo "Error: " . $sql . "<br>" . $conn->error; }. [S1]
  • PDO execution: $conn->exec($sql); echo "New record created successfully"; wrapped in try/catch(PDOException). [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

  • 자동 관리 컬럼 생략 규칙: AUTO_INCREMENT나 기본 타임스탬프를 가진 컬럼은 INSERT 문에 명시하지 않아야 MySQL이 자동으로 값을 채운다는 점이 강조됨. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — MyGuests 테이블에 이름/이메일만 삽입하고 id/reg_date는 자동 처리되는 것이 실전 삽입 패턴이다. [S1]

💻 코드 패턴 (Code patterns)

Inserting a record while omitting auto-managed columns (PHP):

$sql = "INSERT INTO MyGuests (firstname, lastname, email)
        VALUES ('John', 'Doe', 'john@example.com')"; // id, reg_date auto-filled
if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
}
