ServerBCPKeepIdentity Property

Cette fonctionnalité sera supprimée dans une prochaine version de Microsoft SQL Server. Évitez d'utiliser cette fonctionnalité dans de nouveaux travaux de développement et prévoyez de modifier les applications qui utilisent actuellement cette fonctionnalité.

The ServerBCPKeepIdentity property controls the handling of existing values for a column with the identity property when importing data into the column.

.ServerBCPKeepIdentity [= value]

Parts

  • object
    An expression that evaluates to an object in the Applies To list

  • value
    TRUE or FALSE

Data Type

Boolean

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetServerBCPKeepIdentity(LPBOOL pRetVal);
HRESULT SetServerBCPKeepIdentity(BOOL NewValue);

Notes

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.
