SQL UPDATE 저장 표현식이 업데이트되지 않습니다.

Question

저장 프로 시저에서 +10으로 값을 증가 시키려면 매우 간단한 명령문을 사용해야합니다. 그러나 SP를 두 번 이상 실행하면 첫 번째 호출 후에 값이 변경되지 않습니다. 증가 값을 +20으로 수정하면 결과 테이블 값은 테이블에 설정된 ORIGINAL 값의 +20이됩니다.

먼저 게시 한 절차는 StudentCategoryRankTable 다음 삽입 새에있는 모든 항목을 제거합니다. 새 레코드가 업데이트됩니다. 프로 시저를 다시 실행하면 업데이트 된 레코드가 DELETE이되고 시작한 곳으로 돌아갑니다.
