예제

다음 예제에서는 AdventureWorks 샘플 데이터베이스의 원본 테이블에서 동일한 데이터베이스의 대상 테이블로 데이터를 대량 복사합니다. 대상의 열 수가 원본의 열 수와 일치하지만 열 이름과 서수 위치는 일치하지 않습니다. SqlBulkCopyColumnMapping 개체는 대량 복사에 대한 열 맵을 만드는 데 사용됩니다.

중요

이 샘플은 가져올 대량 복사 샘플 설정에 설명된 대로 작업 테이블을 만들지 않은 경우 실행되지 않습니다. 이 코드는 SqlBulkCopy를 사용하는 구문을 보여 주는 용도로 제공됩니다. 원본 테이블과 대상 테이블이 동일한 SQL Server instance 있는 경우 Transact-SQL INSERT … SELECT 문을 사용하여 데이터를 복사하는 것이 더 쉽고 빠릅니다.

SqlBulkCopyColumnMapping(String, Int32)

대상 열에 대한 열 서수와 소스 열을 참조하는 열 이름을 사용하여 새 열 매핑을 만듭니다.

public:
 SqlBulkCopyColumnMapping(System::String ^ sourceColumn, int destinationOrdinal);

public SqlBulkCopyColumnMapping (string sourceColumn, int destinationOrdinal);

new System.Data.SqlClient.SqlBulkCopyColumnMapping : string * int -> System.Data.SqlClient.SqlBulkCopyColumnMapping

Public Sub New (sourceColumn As String, destinationOrdinal As Integer)

매개 변수

sourceColumn

String

데이터 소스 내에 있는 소스 열의 이름입니다.

destinationOrdinal

Int32

대상 테이블 내에 있는 대상 열의 위치입니다.

예제

다음 예제에서는 AdventureWorks 샘플 데이터베이스의 원본 테이블에서 동일한 데이터베이스의 대상 테이블로 데이터를 대량 복사합니다. 대상의 열 수가 원본의 열 수와 일치하지만 열 이름과 서수 위치는 일치하지 않습니다. SqlBulkCopyColumnMapping 개체는 대량 복사에 대한 열 맵을 만드는 데 사용됩니다.

중요

이 샘플은 가져올 대량 복사 샘플 설정에 설명된 대로 작업 테이블을 만들지 않은 경우 실행되지 않습니다. 이 코드는 SqlBulkCopy를 사용하는 구문을 보여 주는 용도로 제공됩니다. 원본 테이블과 대상 테이블이 동일한 SQL Server instance 있는 경우 Transact-SQL INSERT … SELECT 문을 사용하여 데이터를 복사하는 것이 더 쉽고 빠릅니다.
