OdbcTransaction.Commit 메서드

정의

데이터베이스 트랜잭션을 커밋합니다.

public:
 override void Commit();
public:
 virtual void Commit();
public override void Commit ();
public void Commit ();
override this.Commit : unit -> unit
abstract member Commit : unit -> unit
override this.Commit : unit -> unit
Public Overrides Sub Commit ()
Public Sub Commit ()

구현

예외

트랜잭션을 커밋하는 동안 오류가 발생한 경우

트랜잭션이 이미 커밋 또는 롤백된 경우

또는

연결이 손상된 경우
