PostSnapshotScript Property

Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.

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

Sintassi

object.PostSnapshotScript [= value]

Parts

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

  • value
    A string that specifies the complete path and file name of the Transact-SQL script

Data Type

String

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetPostSnapshotScript(SQLDMO_LPBSTR pRetVal);
HRESULT SetPostSnapshotScript(SQLDMO_LPCSTR NewValue);

Osservazioni

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

  • Set up reporting environments that depend on stored procedures.

  • Create custom views.

  • Create user-defined functions.

    [!NOTA]

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

    If an application sets PostSnapshotScript after the initial snapshot has been created, a new snapshot must be generated. Snapshots are applied when the next scheduled snapshot agent runs.

You can also run Transact-SQL scripts during a replication operation using the ReplicateUserDefinedScript method.

[!NOTA]

If an application calls PostSnapshotScript 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.
