適用於：SQL Server Azure SQL 受控執行個體

本主題說明如何使用 SQL Server Management Studio、Transact-SQL 或 Replication Management Objects (RMO)，在 SQL Server 中建立提取訂閱。

為 P2P 複寫設定提取訂閱可透過指令碼來進行，但無法透過精靈進行。

使用 SQL Server Management Studio

使用「新增訂閱精靈」在「發行者」或「訂閱者」端建立提取訂閱。依照精靈中各頁面進行：

指定發行者和發行集。
選取要執行複寫代理程式的位置。對於提取訂閱，根據發行集類型在 [散發代理程式位置] 頁面或 [合併代理程式位置] 頁面上選取 [在訂閱者端執行每一個代理程式 (提取訂閱)] 。
指定訂閱者與訂閱資料庫。
指定複寫代理程式要連接用的登入和密碼：
- 針對快照集和交易式發行集的訂閱，請於 [散發代理程式安全性] 頁面指定認證。
- 針對合併式發行集的訂閱，請於 [合併代理程式安全性] 頁面指定認證。
如需有關各代理程式需要的權限資訊，請參閱＜複寫代理程式安全性模型＞。
指定同步處理排程，以及訂閱者要初始化的時間。
指定合併式發行集的其他選項：訂閱類型；參數化篩選的值；以及如果針對 Web 同步處理啟用該發行集時，透過 HTTPS 同步處理的資訊。
為交易式發行集指定其他選項，以允許更新訂閱：訂閱者是否應立即在發行者端認可變更，或者應寫入佇列；認證用來連接訂閱者和發行者。
選擇性的編寫訂閱指令碼。

若要從發行者建立提取訂閱

連線到 Microsoft SQL Server Management Studio 中的發行者，然後展開伺服器節點。
展開 [複寫] 資料夾，然後展開 [本機發行集] 資料夾。
以滑鼠右鍵按一下您要建立一個或多個訂閱的發行集，然後按一下 [新增訂閱] 。
在新增訂閱精靈中完成頁面。

若要從訂閱者建立提取訂閱

連線到 SQL Server Management Studio 中的訂閱者，然後展開伺服器節點。
展開 [複寫] 資料夾。
以滑鼠右鍵按一下 [區域訂閱] 資料夾，然後按一下 [新增訂閱] 。
在 [新增訂閱精靈] 的 [發行集] 頁面上，從 [發行者] 下拉式清單中選取 <尋找 SQL Server 發行者> 或 <尋找 Oracle 發行者>。
連接到 [連接到伺服器] 對話方塊中的發行者。
選取 [發行集] 頁面上的發行集。
在新增訂閱精靈中完成頁面。

使用 TRANSACT-SQL

您可以使用複寫預存程序以程式設計的方式建立提取訂閱。使用哪些預存程序要依訂閱所屬的發行集類型而定。

若要建立快照式或交易式發行集的提取訂閱

在發行者端，執行 sp_helppublication (Transact-SQL) 來確認發行集可支援提取訂閱。
- 如果結果集中 allow_pull 的值為 1，則發行集支援提取訂閱。
- 如果 allow_pull 的值為 0，請執行 sp_changepublication (Transact-SQL)，並將 @property 指定為 allow_pull，以及將 @value 指定為 true。
在訂閱者端，執行 sp_addpullsubscription (Transact-SQL)。指定 @publisher 和 @publication。如需有關更新訂閱的詳細資訊，請參閱＜建立交易式發行集的可更新訂閱＞。
在訂閱者端，執行 sp_addpullsubscription_agent (Transact-SQL)。指定下列項目：
- @publisher、 @publisher_db和 @publication 參數。
- 執行 [訂閱者] 上的 [散發代理程式] 時會針對 @job_login 和 @job_password 使用 Microsoft Windows 認證。
  
  注意
  
  使用「Windows 整合式驗證」建立的連接一律使用由 @job_login 和 @job_password指定的 Windows 認證。散發代理程式一律使用「Windows 整合式驗證」建立與訂閱者的本機連接。依預設，代理程式會使用「Windows 整合式驗證」連接到「散發者」。
- @distributor_security_mode 的值為 0，以及 @distributor_login 和 @distributor_password 的 SQL Server 登入資訊 (如果您在連線至散發者時需要使用 [SQL Server 驗證])。(選用)
- 此訂閱之散發代理程式作業的排程。如需詳細資訊，請參閱 Specify Synchronization Schedules。
在發行者端，執行 sp_addsubscription (Transact-SQL) 來註冊提取訂閱。指定 @publication、 @subscriber和 @destination_db。為 @subscription_type 指定 pull的值。

若要建立合併式發行集的提取訂閱

在發行者端，執行 sp_helpmergepublication (Transact-SQL) 來確認發行集可支援提取訂閱。
- 如果結果集中 allow_pull 的值為 1，則發行集支援提取訂閱。
- 如果 allow_pull 的值為 0，請執行 sp_changemergepublication (Transact-SQL)，並將 @property 指定為 allow_pull，以及將 @value 指定為 true。
在訂閱者端，執行 sp_addmergepullsubscription (Transact-SQL)。指定 @publisher、 @publisher_db、 @publication和下列參數：
- @subscriber_type：將客訂閱指定為 local，並將主訂閱指定為 global。
- @subscription_priority：指定訂閱的優先權 (0.00 到 99.99)。只需要對主訂閱執行此動作。
  
  如需詳細資訊，請參閱進階合併式複寫衝突偵測與解決。
在訂閱者端，執行 sp_addmergepullsubscription_agent (Transact-SQL)。指定下列參數：
- @publisher、 @publisher_db和 @publication。
- Windows 認證，「訂閱者」上的「合併代理程式」執行時會針對 @job_login 和 @job_password使用該認證。
  
  注意
  
  使用「Windows 整合式驗證」建立的連接一律使用由 @job_login 和 @job_password指定的 Windows 認證。「合併代理程式」一律使用「Windows 整合式驗證」建立到「訂閱者」的本機連接。依預設，代理程式會使用「Windows 整合式驗證」連接到「發行者」。
- @distributor_security_mode 的值為 0，以及 @distributor_login 和 @distributor_password 的 SQL Server 登入資訊 (如果您在連線至散發者時需要使用 [SQL Server 驗證])。(選用)
- (選用) @publisher_security_mode 的 0 值，以及 @publisher_login 和 @publisher_password 的 SQL Server 登入資訊 (如果您在連線到 [發行者] 時需要使用 [SQL Server 驗證])。
- 此訂閱之「合併代理程式」作業的排程。如需詳細資訊，請參閱建立交易式發行集的可更新訂閱。
在發行者端，執行 sp_addmergesubscription (Transact-SQL)。指定 @publication、 @subscriber、 @subscriber_db，並將 @subscription_type 的值指定為 pull。如此會註冊提取訂閱。

範例 (Transact-SQL)

下列範例會建立交易式發行集的提取訂閱。第一批次在「訂閱者」上執行，而第二批次在「發行者」上執行。登入和密碼值是在執行階段使用 sqlcmd 指令碼變數提供的。

使用 Replication Management Objects (RMO)

用於建立提取訂閱的 RMO 類別依該訂閱所屬的發行集類型而定。

若要建立快照式或交易式發行集的提取訂閱

使用 ServerConnection 類別建立與訂閱者和發行者的連接。
使用步驟 1 中的發行者連接建立 TransPublication 類別的執行個體。指定 Name、 DatabaseName 和 ConnectionContext。
呼叫 LoadProperties 方法。如果這個方法傳回 false，則表示步驟 2 中指定的屬性不正確，或伺服器上沒有該發行集存在。
執行位元運算邏輯 AND (Visual C# 中的&和 Visual Basic 中的 And)，位於 Attributes 屬性和 AllowPull 之間。如果結果為 None，則將 Attributes 設為 | 屬性和 Or 之間位元運算邏輯 OR (Visual C# 中的 Attributes ，並將 AllowPull＞。然後呼叫 CommitPropertyChanges 以啟用提取訂閱。
如果訂閱資料庫不存在，可使用 Database 類別建立它。如需詳細資訊，請參閱建立、改變和移除資料庫。
建立 TransPullSubscription 類別的執行個體。
設定下列訂閱屬性：
- 將 ServerConnection 設為到步驟 1 中建立之「訂閱者」的 ConnectionContext。
- 將 DatabaseName設為訂閱資料庫的名稱。
- 將 PublisherName設為「發行者」的名稱。
- 將 PublicationDBName設為發行集資料庫的名稱。
- 將 PublicationName設為發行集的名稱。
- 將 Login，並將 SynchronizationAgentProcessSecurity 的 Password 欄位，為在 [訂閱者] 上執行 [散發代理程式] 時所使用的 Microsoft Windows 帳戶提供認證。此帳戶用於建立到「訂閱者」的本機連接，以及使用「Windows 驗證」建立遠端連接。
  
  注意
  
  當訂閱是由 SynchronizationAgentProcessSecurity 固定伺服器角色的成員建立時，不需要設定 P:Microsoft.SqlServer.Replication.PullSubscription.SynchronizationAgentProcessSecurity ，但還是建議您對其進行設定。在這種情況下，代理程式會模擬「SQL Server Agent」帳戶。如需詳細資訊，請參閱複寫代理程式安全性模型。
- (選擇性) \@value 指定為 CreateSyncAgentByDefault 值，以建立用於同步處理訂閱的代理程式作業。如果指定 false (預設值)，則只能以程式設計的方式同步處理訂閱，而且您在從 TransSynchronizationAgent 屬性存取此物件時必須指定其他屬性 SynchronizationAgent 。如需相關資訊，請參閱 Synchronize a Pull Subscription。
  
  注意
  
  並非所有 Microsoft SQL Server 版本都可使用 SQL Server Agent。如需 SQL Server 版本支援的功能清單，請參閱 SQL Server 2022 的版本和支援功能。當您為 Express 訂閱者指定值 true 時，不會建立代理程式作業。不過，在「訂閱者」上會儲存重要的訂閱相關中繼資料。
- (選擇性) 在使用「SQL Server 驗證」連接到「散發者」時，設定 SqlStandardLogin 的 SqlStandardPassword 和 SecureSqlStandardPassword (或 DistributorSecurity ) 欄位。
呼叫 Create 方法。
使用步驟 2 中 TransPublication 類別的執行個體，呼叫 MakePullSubscriptionWellKnown 方法，以使用「發行者」註冊提取訂閱。如果此註冊已存在，則會發生例外狀況。

若要建立合併式發行集的提取訂閱

使用 ServerConnection 類別建立到「訂閱者」和「發行者」的連接。
使用步驟 1 中的發行者連接建立 MergePublication 類別的執行個體。指定 Name、 DatabaseName和 ConnectionContext。
呼叫 LoadProperties 方法。如果這個方法傳回 false，則表示步驟 2 中指定的屬性不正確，或伺服器上沒有該發行集存在。
執行位元運算邏輯 AND (Visual C# 中的&和 Visual Basic 中的 And)，位於 Attributes 屬性和 AllowPull 之間。如果結果為 None，則將 Attributes 設為 | 屬性和 Or 之間位元運算邏輯 OR (Visual C# 中的 Attributes ，並將 AllowPull＞。然後呼叫 CommitPropertyChanges 以啟用提取訂閱。
如果訂閱資料庫不存在，可使用 Database 類別建立它。如需詳細資訊，請參閱建立、改變和移除資料庫。
建立 MergePullSubscription 類別的執行個體。
設定下列訂閱屬性：
- 將 ServerConnection 設為到步驟 1 中建立之「訂閱者」的 ConnectionContext。
- 將 DatabaseName設為訂閱資料庫的名稱。
- 將 PublisherName設為「發行者」的名稱。
- 將 PublicationDBName設為發行集資料庫的名稱。
- 將 PublicationName設為發行集的名稱。
- 將 Login，並將 SynchronizationAgentProcessSecurity 的 Password 欄位，為在 [訂閱者] 上執行 [合併代理程式] 時所使用的 Microsoft Windows 帳戶提供認證。此帳戶用於建立到「訂閱者」的本機連接，以及使用「Windows 驗證」建立遠端連接。
  
  注意
  
  當訂閱是由 SynchronizationAgentProcessSecurity 固定伺服器角色的成員建立時，不需要設定 P:Microsoft.SqlServer.Replication.PullSubscription.SynchronizationAgentProcessSecurity ，但還是建議您對其進行設定。在這種情況下，代理程式會模擬「SQL Server Agent」帳戶。如需詳細資訊，請參閱複寫代理程式安全性模型。
- (選擇性) \@value 指定為 CreateSyncAgentByDefault 值，以建立用於同步處理訂閱的代理程式作業。如果指定 false (預設值)，則只能以程式設計的方式同步處理訂閱，而且您在從 MergeSynchronizationAgent 屬性存取此物件時必須指定其他屬性 SynchronizationAgent 。如需相關資訊，請參閱 Synchronize a Pull Subscription。
- (選擇性) 在使用「SQL Server 驗證」連接到「散發者」時，設定 SqlStandardLogin 的 SqlStandardPassword 和 SecureSqlStandardPassword (或 DistributorSecurity ) 欄位。
- (選擇性) 在使用「SQL Server 驗證」連接到「發行者」時，設定 SqlStandardLogin 的 SqlStandardPassword 和 SecureSqlStandardPassword (或 PublisherSecurity ) 欄位。
呼叫 Create 方法。
使用步驟 2 中 MergePublication 類別的執行個體，呼叫 MakePullSubscriptionWellKnown 方法，以使用「發行者」註冊提取訂閱。如果此註冊已存在，則會發生例外狀況。
