PrimaryFile 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 PrimaryFile property identifies the operating system file that maintains database-specific system tables.

Syntaxe

object.PrimaryFile [= value]

Parts

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

• value
  TRUE or FALSE

Notes

A Microsoft SQL Server database can have, at most, one primary file. When a database is created using SQL Distributed Management Objects (SQL-DMO), the first DBFile object named PRIMARY added to the DBFiles collection of the FileGroup object referencing the filegroup becomes the primary file. Set the PrimaryFile property to alter the default behavior.

Data Type

Boolean

Modifiable

Read/write prior to database creation. Read-only after database creation.

Prototype (C/C++)

HRESULT GetPrimaryFile(LPBOOL pRetVal);
HRESULT SetPrimaryFile(BOOL NewValue);

Notes

Running Transact-SQL scripts before an initial snapshot is applied can be used to:

• Perform presnapshot cleanup.

• Add users and permissions to databases to be replicated.

• Create user-defined data types.

  [!REMARQUE]

  If PreSnapshotScript is set, the script automatically runs when a subscription is reinitialized. Therefore, the script must be written so that its statements are repeatable.
