Hinweise
If TRUE, the BulkCopy object uses an application-initiated connection. The connection used is determined by the Table or View object referenced in the ImportData or ExportData method call.
If FALSE (default), the BulkCopyobject specifies an operation implemented using an additional, connection initiated by SQL Distributed Management Objects (SQL-DMO) to the source or target instance of Microsoft SQL Server.

---|
To perform bulk-copy operations using the BulkCopy object, the SQL-DMO application connection to an instance of SQL Server must be enabled. To enable a connection for bulk copy, set the EnableBcp property of the SQLServer object. The UseExistingConnection property of the BulkCopy object does not enable a connection for bulk-copy operations. |
