TransPublication Object

Esta característica se quitará en una versión futura de Microsoft SQL Server. Evite utilizar esta característica en nuevos trabajos de desarrollo y tenga previsto modificar las aplicaciones que actualmente la utilizan.

The TransPublication object represents a transactional or snapshot publication. A publication contains one or more articles (tables or stored procedures) that contain replicated data.

Notas

With the TransPublication object, you can:

• Create a transactional publication.
• Change the properties of an existing transactional publication.
• Enable a transactional publication after all articles are added.
• Create a snapshot publication.
• Change the properties of an existing snapshot publication.
• Enable a snapshot publication after all articles are added.

[!NOTA] The TransPublication object is compatible with instances of SQL Server versions 7.0 and later. However, the TransPublication2 object extends the functionality of the TransPublication object for use with features that were introduced in SQL Server 2000.

To create a transactional publication

1. Create a new TransPublication object.

2. Set the Name property.

3. Note that the ReplicationFrequency property defaults to SQLDMORepFreq_Continuous, which specifies a transactional publication.

4. Set the PublicationAttributes property as appropriate.

   • To enable push subscriptions, use SQLDMOPubAttrib_AllowPush.
   • To enable pull subscriptions, use SQLDMOPubAttrib_AllowPull.
   • To enable anonymous subscriptions, use SQLDMOPubAttrib_AllowPull, SQLDMOPubAttrib_AllowAnonymous, and SQLDMOPubAttrib_ImmediateSync.
   • To enable Internet subscriptions, use SQLDMOPubAttrib_InternetEnabled.

5. Add the TransPublication object to the TransPublications collection of a connected ReplicationDatabase object.

To alter a transactional publication

1. Get a TransPublication object from the TransPublications collection of a connected ReplicationDatabase object.

2. Use the BeginAlter method to mark the beginning of the changes.

3. Set the TransPublication object properties to reflect the changes to the transactional publication.

4. Use the DoAlter method to submit the changes to Microsoft SQL Server.

To enable a transactional publication after all articles have been added

1. Get a TransPublication object from the TransPublications collection of a connected ReplicationDatabase object.

2. Set the Enabled property to TRUE.

To create a snapshot publication

1. Create a new TransPublication object.

2. Set the Name property.

3. Set the ReplicationFrequency property to SQLDMORepFreq_Snapshot.

4. Set the PublicationAttributes property as appropriate.

   • To enable push subscriptions, use SQLDMOPubAttrib_AllowPush.
   • To enable pull subscriptions, use SQLDMOPubAttrib_AllowPull.
   • To enable anonymous subscriptions, use SQLDMOPubAttrib_AllowPull, SQLDMOPubAttrib_AllowAnonymous, and SQLDMOPubAttrib_ImmediateSync.
   • To enable Internet subscriptions, use SQLDMOPubAttrib_InternetEnabled.

5. Add the TransPublication object to the TransPublications collection of a connected ReplicationDatabase object.

To alter a snapshot publication

1. Get a TransPublication object from the TransPublications collection of a connected ReplicationDatabase object.

2. Use the BeginAlter method to mark the beginning of the changes.

3. Set the TransPublication object properties to reflect the changes to the snapshot publication.

4. Use the DoAlter method to submit the changes to SQL Server.

To enable a snapshot publication after all articles have been added
