WriteToServer(DataTable, DataRowState)	제공된 DataTable 제공된 행 상태와 일치하는 행만 SqlBulkCopy 개체의 DestinationTableName 속성으로 지정된 대상 테이블에 복사합니다.
WriteToServer(IDataReader)	제공된 IDataReader 모든 행을 SqlBulkCopy 개체의 DestinationTableName 속성으로 지정된 대상 테이블에 복사합니다.
WriteToServer(DataTable)	제공된 DataTable 모든 행을 SqlBulkCopy 개체의 DestinationTableName 속성으로 지정된 대상 테이블에 복사합니다.
WriteToServer(DbDataReader)	제공된 DbDataReader 배열의 모든 행을 SqlBulkCopy 개체의 DestinationTableName 속성으로 지정된 대상 테이블에 복사합니다.
WriteToServer(DataRow[])	제공된 DataRow 배열의 모든 행을 SqlBulkCopy 개체의 DestinationTableName 속성으로 지정된 대상 테이블에 복사합니다.

설명

MARS(여러 활성 결과 집합)를 사용하지 않도록 설정하면 WriteToServer 연결을 사용할 수 없게 됩니다. MARS를 사용하는 경우 동일한 연결의 다른 명령과 WriteToServer 호출을 인터리브할 수 있습니다.

WriteToServer(DataTable, DataRowState)

제공된 DataTable 제공된 행 상태와 일치하는 행만 SqlBulkCopy 개체의 DestinationTableName 속성으로 지정된 대상 테이블에 복사합니다.

public:
 void WriteToServer(System::Data::DataTable ^ table, System::Data::DataRowState rowState);

public void WriteToServer (System.Data.DataTable table, System.Data.DataRowState rowState);

member this.WriteToServer : System.Data.DataTable * System.Data.DataRowState -> unit

Public Sub WriteToServer (table As DataTable, rowState As DataRowState)

매개 변수

table

DataTable

행이 대상 테이블에 복사되는 DataTable.

rowState

DataRowState

DataRowState 열거형의 값입니다. 행 상태와 일치하는 행만 대상에 복사됩니다.

예제

다음 콘솔 애플리케이션은 지정된 상태와 일치하는 DataTable 행만 대량 로드하는 방법을 보여 줍니다. 이 경우 변경되지 않은 행만 추가됩니다. 대상 테이블은 AdventureWorks 데이터베이스의 테이블입니다.

이 예제에서는 런타임에 DataTable 만들어지고 세 개의 행이 추가됩니다. WriteToServer 메서드를 실행하기 전에 행 중 하나가 편집됩니다. WriteToServer 메서드는 DataRowState.UnchangedrowState 인수를 사용하여 호출되므로 변경되지 않은 두 행만 대상에 대량 복사됩니다.

중요하다

이 샘플은 대량 복사 예제 설치설명된 대로 작업 테이블을 만들지 않은 한 실행되지 않습니다. 이 코드는 SqlBulkCopy 사용하기 위한 구문을 보여 줍니다. 원본 및 대상 테이블이 동일한 SQL Server 인스턴스에 있는 경우 Transact-SQL INSERT ... SELECT 문을 사용하여 데이터를 복사하는 것이 더 쉽고 빠릅니다.

설명

복사 작업은 판독기에서 사용 가능한 다음 행에서 시작됩니다. 대부분의 경우 판독기는 ExecuteReader 또는 유사한 호출에 의해 반환되었으므로 사용 가능한 다음 행은 첫 번째 행입니다. 여러 결과를 처리하려면 데이터 판독기에서 NextResult 호출하고 WriteToServer 다시 호출합니다.

WriteToServer 사용하면 판독기의 상태가 수정됩니다. 메서드는 false를 반환하거나 작업이 중단되거나 오류가 발생할 때까지 Read 호출합니다. 즉, 데이터 판독기는 WriteToServer 작업이 완료되면 결과 집합이 끝날 때 다른 상태에 있을 수 있습니다.

대량 복사 작업이 진행 중인 동안 연결된 대상 SqlConnection 처리 중이며 연결에 대해 다른 작업을 수행할 수 없습니다.

ColumnMappings 컬렉션은 데이터 판독기 열에서 대상 데이터베이스 테이블로 매핑됩니다.

설명

DataTable 모든 행은 삭제된 행을 제외하고 대상 테이블에 복사됩니다.

대량 복사 작업이 진행 중인 동안 연결된 대상 SqlConnection 처리 중이며 연결에 대해 다른 작업을 수행할 수 없습니다.

ColumnMappings 컬렉션은 DataTable 열에서 대상 데이터베이스 테이블로 매핑됩니다.

추가 정보

• SQL Server 대량 복사 작업
• ADO.NET 개요

WriteToServer(DbDataReader)

제공된 DbDataReader 배열의 모든 행을 SqlBulkCopy 개체의 DestinationTableName 속성으로 지정된 대상 테이블에 복사합니다.

public:
 void WriteToServer(System::Data::Common::DbDataReader ^ reader);

public void WriteToServer (System.Data.Common.DbDataReader reader);

member this.WriteToServer : System.Data.Common.DbDataReader -> unit

Public Sub WriteToServer (reader As DbDataReader)

매개 변수

reader

DbDataReader

행이 대상 테이블에 복사되는 DbDataReader.

WriteToServer(DataRow[])

제공된 DataRow 배열의 모든 행을 SqlBulkCopy 개체의 DestinationTableName 속성으로 지정된 대상 테이블에 복사합니다.

public:
 void WriteToServer(cli::array <System::Data::DataRow ^> ^ rows);

public void WriteToServer (System.Data.DataRow[] rows);

member this.WriteToServer : System.Data.DataRow[] -> unit

Public Sub WriteToServer (rows As DataRow())

매개 변수

rows

DataRow[]

대상 테이블에 복사할 DataRow 개체의 배열입니다.

예제

다음 콘솔 애플리케이션은 DataRow 배열에서 데이터를 대량 로드하는 방법을 보여 줍니다. 대상 테이블은 AdventureWorks 데이터베이스의 테이블입니다.

이 예제에서는 런타임에 DataTable 만들어집니다. 대상 테이블에 복사할 DataTable 단일 행이 선택됩니다.

중요하다

이 샘플은 대량 복사 예제 설치설명된 대로 작업 테이블을 만들지 않은 한 실행되지 않습니다. 이 코드는 SqlBulkCopy 사용하기 위한 구문을 보여 줍니다. 원본 및 대상 테이블이 동일한 SQL Server 인스턴스에 있는 경우 Transact-SQL INSERT ... SELECT 문을 사용하여 데이터를 복사하는 것이 더 쉽고 빠릅니다.
