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.
