Integration Services 组件未安装或您无权使用它

Question

因为我使用 SMO 将数据从一个数据库复制到另一个数据库。我使用了我自己的数据库助手 class。传输数据时出现异常。

Integration Services 组件未安装或您没有使用它的权限。

我的代码如下：

public class DBHelper
{
    #region Private Variables
    private static string sourceSQLServer;
    private static string destinationSQLServer;
    private static string sourceDatabase;
    private static string destinationDatabase;
    #endregion

    #region Properties

    /// <summary>
    /// SourceSQLServer Holds Instance Name of Source SQL Server Database Name
    /// </summary>
    public static string SourceSQLServer
    {
        get { return DBHelper.sourceSQLServer; }
        set { DBHelper.sourceSQLServer = value; }
    }

    /// <summary>
    /// DestinationSQLServer Holds Instance Name of Destination SQL Server Database Name
    /// </summary>
    public static string DestinationSQLServer
    {
        get { return DBHelper.destinationSQLServer; }
        set { DBHelper.destinationSQLServer = value; }
    }

    /// <summary>
    /// SourceDatabase Holds Source Database 
    /// </summary>
    public static string SourceDatabase
    {
        get { return DBHelper.sourceDatabase; }
        set { DBHelper.sourceDatabase = value; }
    }

    /// <summary>
    /// DestinationDatabase Holds Destination Database Name
    /// </summary>
    public static string DestinationDatabase
    {
        get { return DBHelper.destinationDatabase; }
        set { DBHelper.destinationDatabase = value; }
    }
    #endregion

    #region Static Methods
    /// <summary>
    ///  CopyDatabase Copies Database 
    /// </summary>
    /// <param name="CopyData">True if Want to Copy Data otherwise False</param>
    public static void CopyDatabase(bool bCopyData)
    {
        //Set Source SQL Server Instance Information
        Server server = new Server(DBHelper.SourceSQLServer);

        //Set Source Database Name [Database to Copy]
        Database database = server.Databases[DBHelper.SourceDatabase];

        //Set Transfer Class Source Database
        Transfer transfer = new Transfer(database);

        //Yes I want to Copy All the Database Objects
        transfer.CopyAllObjects = true;

        //In case if the Destination Database / Objects Exists Drop them First
        transfer.DropDestinationObjectsFirst = true;

        //Copy Database Schema
        transfer.CopySchema = true;

        //Copy Database Data Get Value from bCopyData Parameter
        transfer.CopyData = bCopyData;

        //Set Destination SQL Server Instance Name
        transfer.DestinationServer = DBHelper.DestinationSQLServer;

        //Create The Database in Destination Server
        transfer.CreateTargetDatabase = true;

        //Set Destination Database Name
        Database ddatabase = new Database(server, DBHelper.DestinationDatabase);

        //Create Empty Database at Destination
        ddatabase.Create();

        //Set Destination Database Name
        transfer.DestinationDatabase = DBHelper.DestinationDatabase;

        //Include If Not Exists Clause in the Script
        transfer.Options.IncludeIfNotExists = true;

        //Start Transfer
        transfer.TransferData();

        //Release Server variable
        server = null;
    }
    #endregion
}

在 Main 函数上我调用这个

DBHelper.SourceSQLServer = @"DESKTOP-PCEOPRM\SQLEXPRESS";

//Set Your Database Name Here (To Be Copied or Scripted)
DBHelper.SourceDatabase = "MetisEmptyDB";

////Set Destination SQL Server Name Here
DBHelper.DestinationSQLServer = @"DESKTOP-PCEOPRM\SQLEXPRESS";

//Set New Database Name Here 
DBHelper.DestinationDatabase = "NewDb";

//Set True if you want to copy Data
//Set False if you want to copy Only Schema
DBHelper.CopyDatabase(true);
Console.WriteLine("Scripting Finished");

提前致谢。如果您发现任何其他替代方法可以从 C# 中的现有数据库创建新数据库，请也分享代码。

Answer 1

线索就在错误中。您正在尝试使用 SQL Server Integration Services 的代码，但 SQL Server Express 中不包含该代码。

此外，使用 T-SQL 这些事情也容易得多。您可以轻松地创建新的空数据库并编写对象脚本。或者备份和恢复数据库。

我不应该 post Whosebug 中的代码，因为在 dba.stackexchange.com

会更好地询问它

BACKUP DATABASE AdventureWorks2012   
 TO DISK = 'C:\SQLServerBackups\AdvWorksData.bak' 
 WITH FORMAT;

并在另一台服务器上恢复

RESTORE DATABASE AdventureWorks2012  
  FROM DISK = 'C:\SQLServerBackups\AdventureWorks2012.bak';

在尝试通过 C# 执行此操作之前，请确保您了解 SQL 中的操作。如果您按照前面问题中的建议使用 SQLCMD 手动完成所有 sql，您将了解有关 SQL 的更多信息。

Answer 2

对我来说，当我将依赖项从 SQL Server 2008 Express 更改为 SQL Server 2012 Express 时，这个错误就消失了。

我引用了

中的程序集

C:\Program Files (x86)\Microsoft SQL Server0\SDK\Assemblies

不是

C:\Program Files (x86)\Microsoft SQL Server0\SDK\Assemblies

如果您能够更改依赖关系，那么它就可以工作。
