ServerBCPKeepIdentity Property
Diese Funktion wird in zukünftigen Versionen von Microsoft SQL Server nicht mehr bereitgestellt. Verwenden Sie diese Funktion beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.
The ServerBCPKeepIdentity property controls the handling of existing values for a column with the identity property when importing data into the column.

Hinweise
If TRUE, SQL Distributed Management Objects (SQL-DMO) executes a SET IDENTITY_INSERT ON statement when the ImportData method of a Table object is called. Values for the identity column existing in the data file are copied to the referenced table's identity column.
If FALSE, SQL-DMO ignores any data values present for a column with the identity property. Microsoft SQL Server generates data values for the column using the column's setting for identity seed and increment. The default is FALSE.
The ServerBCPKeepIdentity property is interpreted only when data is imported and if the UseServerSideBCP property of the BulkCopy object is TRUE.
