PreSnapshotScript 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 PreSnapshotScript property specifies the complete path and file name of a Transact-SQL script that runs before an initial snapshot is applied to a Subscriber.

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.
If an application sets **PreSnapshotScript** after the initial snapshot has been created, a new snapshot must be generated. Snapshots are applied when the next scheduled snapshot agent runs..gif "ms133566.note(fr-fr,SQL.90).gif")
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.
You can also run Transact-SQL scripts during a replication operation using the ReplicateUserDefinedScript method.
| Remarque : |
|---|
| If an application calls PreSnapshotScript on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned. |
