ReplicationFrequency 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 ReplicationFrequency property sets the method used to determine article publication.
Syntaxe
object.ReplicationFrequency [= value]
Parts
object
An expression that evaluates to an object in the Applies To list.value
A long integer that specifies article publication as described in Settings.
Data Type
Long, enumerated
Modifiable
Read/write when using the SQL Distributed Management Objects (SQL-DMO) object to create a publication.
Read-only when the object references an existing publication.
Prototype (C/C++)
HRESULT GetReplicationFrequency(SQLDMO_REPFREQ_TYPE* pRetVal);
HRESULT SetReplicationFrequency(SQLDMO_REPFREQ_TYPE NewValue);
Settings
Constant |

SQLDMORepFreq_Continuous |
0 |
Log monitoring or another method is used to determine replicated article content. |
SQLDMORepFreq_Snapshot |

The value is not valid. |
Notes
Microsoft SQL Server supports two types of transactional replication. In the first instance, data is replicated at fixed intervals regardless of any changes made to that data. This type of transactional replication is more often identified as snapshot replication, because the data is simply copied as it exists at a given moment. Transactional replication can also determine replicated values based on changes made to that data. By default, SQL Server replication monitors changes to the transaction log of a database to determine which values are replicated.
Setting the ReplicationFrequency property controls the type of transactional replication defined by the TransPublication object and is part of creating transactional and snapshot replication publications. For more information, see TransPublication Object.
