oracle 저장 과정 중if 문장

1. 전체 스토리지 프로세스는 다음과 같습니다.
이 저장 프로세스는 내용이 좀 많을 수 있습니다. 이것은 제가 평소에 사용하던 저장 프로세스입니다. 마침 안에if문장이 사용되었기 때문에 제가 가져와서 여러분께 보여 드리겠습니다.

2. 주의해야 할 점
글을 쓸 때 여러 가지 상황이 있으면 반드시 사용하지 마라else if. 이런 용법은oracle 저장 과정에서 잘못된 것이기 때문에 사용해야 한다elsif. 처음 사용할 때 내가 잘못 썼기 때문에 아무리 조정해도 틀릴 수 있다. 마지막에 이것이 문제가 있다는 것을 알게 되었다.그래서 정확한 용법은 다음과 같다.

  if p_info101 = '0' then
    m_info101_word := '   ';
  elsif p_info101 = '1' then
    m_info101_word := '   ';
  elsif p_info101 = '2' then
    m_info101_word := '   ';
  
  end if;

또 하나 저장 과정 중의 판단이 동일한지 여부=를 판단하고 변수에 값을 부여할 때:=를 사용한다.
