備註
Synchronize在傳回的物件上呼叫 TransSynchronizationAgent 方法,以同步處理訂閱。
在抓取 CommitPropertyChanges SynchronizationAgent 以同步處理訂閱之前,呼叫以儲存伺服器上的任何屬性變更。
如果建立的提取訂閱的值為 false CreateSyncAgentByDefault ,則預設為不會建立訂閱的散發代理程式作業。 您可能需要在傳回的物件上指定其他屬性,才能 TransSynchronizationAgent 用來同步處理訂閱。
只有在訂閱者端的 SynchronizationAgent sysadmin 固定伺服器角色成員,或 db_owner 訂閱資料庫的固定資料庫角色成員,才能抓取此屬性。
抓取 SynchronizationAgent 屬性相當於執行 sp_helppullsubscription。
