예제

다음 예제에서는 a 및 .를 SqlConnectionSqlTransaction만듭니다. 또한 , Commit및 Rollback 메서드를 BeginTransaction사용하는 방법을 보여 줍니다. 트랜잭션은 오류가 발생하거나 먼저 커밋되지 않고 삭제된 경우 롤백됩니다. Try / Catch 오류 처리는 트랜잭션을 커밋하거나 롤백하려고 할 때 오류를 처리하는 데 사용됩니다.

설명

애플리케이션은 개체를 SqlTransaction 호출 BeginTransaction 하여 개체를 SqlConnection 만듭니다. 트랜잭션과 연결된 모든 후속 작업(예: 트랜잭션 커밋 또는 중단)은 개체에서 SqlTransaction 수행됩니다.

SQL Server 트랜잭션에 대한 자세한 내용은 Explicit Transactions 및 Coding Efficient Transactions 참조하세요.
