Public Overridable Function InsertHandler (insertSource As SourceIdentifier, insertedDataSet As DataSet, ByRef customDataSet As DataSet, ByRef historyLogLevel As Integer, ByRef historyLogMessage As String) As ActionOnDataChange

매개 변수

insertSource
SourceIdentifier

삽입이 게시자에서 시작되었는지 아니면 구독자에서 시작되었는지를 정의하는 SourceIdentifier입니다.

insertedDataSet
DataSet

삽입된 행의 GUID를 포함하는 데이터 집합입니다.

customDataSet
DataSet

사용자 지정 비즈니스 논리가 반환하는 수정된 행을 포함하는 데이터 집합입니다.

historyLogLevel
Int32

사용자 지정 비즈니스 논리가 반환하는 사용자 지정 메시지의 로그 수준입니다.

historyLogMessage
String

사용자 지정 비즈니스 논리가 제공하는 로그 메시지입니다. 이 로그 메시지는 배포 데이터베이스에 기록됩니다.

반환

사용자 지정 비즈니스 논리가 실행된 후 프로세스에서 수행할 ActionOnDataChange 동작입니다.
