Define el tipo de archivo que proporciona los datos de origen.

public enum class DTSBulkInsert_DataFileType
public enum DTSBulkInsert_DataFileType
type DTSBulkInsert_DataFileType = 
Public Enum DTSBulkInsert_DataFileType
Herencia
DTSBulkInsert_DataFileType

Campos

DTSBulkInsert_DataFileType_Char 0

Formato de caracteres (valor predeterminado).

DTSBulkInsert_DataFileType_Native 1

Tipos de datos nativos (base de datos). Cree el archivo de datos nativo copiando datos de forma masiva desde SQL Server mediante la utilidad bcp.

DTSBulkInsert_DataFileType_WideChar 2

Caracteres Unicode.

DTSBulkInsert_DataFileType_WideNative 3

Tipos de datos nativos (base de datos), excepto en las columnas char, varchar y text, que almacenan datos como Unicode. Cree el archivo de datos widenative copiando datos de forma masiva desde SQL Server mediante la utilidad bcp.

Ejemplos

En el ejemplo siguiente se crea un BulkInsertTaskobjeto y, a continuación, se muestra la configuración predeterminada de las propiedades mediante TaskHost. A continuación, establece dos campos, uno de ellos como DataFileType, que usa esta enumeración, para mostrar cómo establecer valores de campo.
