匯入資料層應用程式 (DAC) 檔案 (.bacpac 檔案),可在新的 Database EngineDatabase Engine 執行個體上,建立原始資料庫連同其資料的複本,或將該檔案匯入 Azure SQL DatabaseAzure SQL DatabaseImport a data-tier application (DAC) file - a .bacpac file - to create a copy of the original database, with the data, on a new instance of the Database EngineDatabase Engine, or to Azure SQL DatabaseAzure SQL Database. 匯出-匯入作業可以進行合併以在執行個體之間移轉 DAC 或資料庫,或建立邏輯備份 (例如建立 SQL DatabaseSQL Database 中所部署資料庫的內部部署複本)。Export-import operations can be combined to migrate a DAC or database between instances, or to create a logical backup, such as creating an on-premises copy of a database deployed in SQL DatabaseSQL Database.

開始之前Before You Begin

匯入程序會使用兩個階段來建立新的 DAC。The import process builds a new DAC in two stages.

  1. 匯入會使用儲存在匯出檔案中的 DAC 定義,建立新的 DAC 及相關聯的資料庫,其方式相當於 DAC 部署從 DAC 封裝檔案中的定義建立新的 DAC。The import creates a new DAC and associated database using the DAC definition stored in the export file, the same way a DAC deploy creates a new DAC from the definition in a DAC package file.

  2. 匯入會從匯出檔案大量複製資料。The import bulk copies in the data from the export file.

SQL Server 公用程式SQL Server Utility

如果您將 DAC 匯入至資料庫引擎執行個體,下次從執行個體將公用程式收集組傳送到公用程式控制點時,匯入的 DAC 就會合併至 SQL Server 公用程式。If you import a DAC to an instance of the Database Engine, the imported DAC is incorporated into the SQL Server Utility the next time the utility collection set is sent from the instance to the utility control point. 然後 DAC 會出現在 Management StudioManagement Studio [公用程式總管] 的 [部署的資料層應用程式] 節點中,並在 [部署的資料層應用程式] 詳細資料頁面中報告。The DAC will then be present in the Deployed Data-tier Applications node of the Management StudioManagement Studio Utility Explorer and reported in the Deployed Data-tier Applications details page.

資料庫選項和設定Database Options and Settings

根據預設,匯入期間建立的資料庫將會擁有 CREATE DATABASE 陳述式中的所有預設值,但是資料庫定序和相容性層級會設定為 DAC 匯出檔案中所定義的值。By default, the database created during the import will have all of the default settings from the CREATE DATABASE statement, except that the database collation and compatibility level are set to the values defined in the DAC export file. DAC 匯出檔案使用原始資料庫中的值。A DAC export file uses the values from the original database.

某些資料庫選項 (例如 TRUSTWORTHY、DB_CHAINING 和 HONOR_BROKER_PRIORITY) 無法在匯入過程中調整。Some database options, such as TRUSTWORTHY, DB_CHAINING, and HONOR_BROKER_PRIORITY, cannot be adjusted as part of the import process. 實體屬性 (如檔案群組數目或檔案數目和大小) 無法在匯入過程中更改。Physical properties, such as the number of filegroups, or the numbers and sizes of files cannot be altered as part of the import process. 匯入完成之後,您可以使用 ALTER DATABASE 陳述式、 SQL Server Management StudioSQL Server Management StudioSQL ServerSQL Server PowerShell 來調整資料庫。After the import completes, you can use the ALTER DATABASE statement, SQL Server Management StudioSQL Server Management Studio, or SQL ServerSQL Server PowerShell to tailor the database. 如需詳細資訊,請參閱 DatabasesFor more information, see Databases.

限制事項Limitations and restrictions

DAC 可匯入至 SQL DatabaseSQL Database或執行 Database EngineDatabase Engine Service Pack 4 (SP4) 或更新版本的 SQL Server 2005 (9.x)SQL Server 2005 (9.x) 執行個體。A DAC can be imported to SQL DatabaseSQL Database, or an instance of the Database EngineDatabase Engine running SQL Server 2005 (9.x)SQL Server 2005 (9.x) Service Pack 4 (SP4) or later. 如果您從更新版本匯出 DAC,則 DAC 可能會包含 SQL Server 2005 (9.x)SQL Server 2005 (9.x)不支援的物件。If you export a DAC from a higher version, the DAC may contain objects not supported by SQL Server 2005 (9.x)SQL Server 2005 (9.x). 您無法將這些 DAC 部署至 SQL Server 2005 (9.x)SQL Server 2005 (9.x)執行個體。You cannot deploy those DACs to instances of SQL Server 2005 (9.x)SQL Server 2005 (9.x).


建議您不要匯入來源不明或來源不受信任的 DAC 匯出檔案。We recommend that you do not import a DAC export file from unknown or untrusted sources. 這類檔案可能包含惡意程式碼,因此可能會執行非預期的 Transact-SQL 程式碼,或是修改結構描述而造成錯誤。Such files could contain malicious code that might execute unintended Transact-SQL code or cause errors by modifying the schema. 在您使用來源不明或來源不受信任的匯出檔案之前,請解除封裝 DAC 並檢查程式碼,例如預存程序和其他使用者定義的程式碼。Before you use an export file from an unknown or untrusted source, unpack the DAC and examine the code, like stored procedures and other user-defined code. 如需有關如何執行這些檢查的詳細資訊,請參閱< Validate a DAC Package>。For more information about how to perform these checks, see Validate a DAC Package.


為了提高安全性,SQL Server 驗證登入會儲存在 DAC 匯出檔案中,而且沒有密碼。To improve security, SQL Server Authentication logins are stored in a DAC export file without a password. 當您匯入檔案之後,此登入會建立為停用的登入,而且會產生密碼。When the file is imported, the login is created as a disabled login with a generated password. 若要啟用登入,請使用具有 ALTER ANY LOGIN 權限的登入進行登入,並使用 ALTER LOGIN 來啟用登入,然後指派可以傳達給使用者的新密碼。To enable the logins, sign in using a login that has ALTER ANY LOGIN permission and use ALTER LOGIN to enable the login and assign a new password that can be communicated to the user. Windows 驗證登入不需要這項處理,因為這類登入的密碼不是由 SQL Server 所管理。This is not needed for Windows Authentication logins because their passwords are not managed by SQL Server.


只有 系統管理員 (sysadmin)serveradmin 固定伺服器角色的成員,或是具有 dbcreator 固定伺服器角色且擁有 ALTER ANY LOGIN 權限的登入,才能匯入 DAC。A DAC can only be imported by members of the sysadmin or serveradmin fixed server roles, or by logins that are in the dbcreator fixed server role and have ALTER ANY LOGIN permissions. 內建的 SQL ServerSQL Server 系統管理員帳戶 (名稱為 sa ) 也可以匯入 DAC。The built-in SQL ServerSQL Server system administrator account named sa can also import a DAC. 將具有登入的 DAC 匯入至 SQL DatabaseSQL Database ,需要 loginmanager 或 serveradmin 角色的成員資格。Importing a DAC with logins to SQL DatabaseSQL Database requires membership in the loginmanager or serveradmin roles. 將不具有登入的 DAC 匯入至 SQL DatabaseSQL Database ,需要 dbmanager 或 serveradmin 角色的成員資格。Importing a DAC without logins to SQL DatabaseSQL Database requires membership in the dbmanager or serveradmin roles.
