[Oracle] PL/SQL -TRIGGER 개념과 예제

위의 포스팅에 트리거에 대해 나와있으니 확인하면 될 것 같습니다.

 

 

 

# 스프링 구조

1. Spring Container : 사용자 정의 클래스를 관리 (생성, 소멸)
   = ApplicationContext
   = WebApplicationContext
   = AnnotationConfigApplicationContext
2. 생성시에 필요한 데이터 전송
   DI => setXxx(), 생성자의 매개변수
    p:   c:
3. AOP : 중복 제거(자동 호출)
     => 시점, 메소드 호출

 

 

# 트리거 특징 

 - 자동으로 실행되며 수동으로는 실행할 수 없음
 - 어떤 동작에서 실행되는지 지정해야함
 - 작동이 일어난 트리거 대상 테이블에 대해서는 트리거 내용이 존재할 수 없음
 - BEFORE / AFTER 두 가지
 - 트랜잭션 일부로 처리 (COMMIT/ROLLBACK/SAVEPOINT 문장 포함 못함)
