Programmatically Transfer SQL Server Objects (Views) Using C#

This article explains how to Programmatically create an SQL Server Integration Services (SSIS) package with a Transfer SQL Server Objects component. The Transfer SQL Server Objects tasks allows ETL developers to copy one or more Microsoft SQL server objects (i.e. views, stored procedures, tables, schema etc) into another SQL instance. For the purposes of this research, the article will explain how to transfer a SQL Server Views from one instance into another.

If the above requirements are all met, we will begin by launching Microsoft Visual Studio edition.
Create a new project Integration Services Project which is located under Business Intelligence Projects.
After you have named the new project, proceed to click and drag the script task in Control Flow pane of the new package.
Right click the script task and click on “Edit”
Under the Script Task Editor change the “ScriptLanguage” to “Microsoft Visual C# 2008”.
In Project Explorer import relevant references and ensure that you have declared namespaces as below:
using System;
using System.Data;
using System.Data.Sql;
using System.Data.SqlTypes;
using System.Data.SqlClient;
using Microsoft.SqlServer.Server;
using Microsoft.SqlServer.Dts.Tasks;
using Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using RuntimeWrapper = Microsoft.SqlServer.Dts.Runtime.Wrapper;
using System.IO;
After declarations, create an instance of application and package:

Application SIFISO_app = new Application();
Package p = new Package();

Declare an SMO server connection for both source and destionation server:

ConnectionManager src_cm = p.Connections.Add(“SMOServer”);
src_cm.Name = “source_conn”;
src_cm.ConnectionString = string.Format(“SqlServerName={0}; UseWindowsAuthentication={1};”, “your_source_server”, “True”);

ConnectionManager des_cm = p.Connections.Add(“SMOServer”);
des_cm.Name = “des_conn”;
des_cm.ConnectionString = string.Format(“SqlServerName={0}; UseWindowsAuthentication={1};”, “your_destination_server”, “True”);
Declare variable that will be used to capture view names to be transferred and assign values to the newly declared variable:

string view_list_names = “[dbo].[vTimeSeries]”;
StringCollection tb_Col = new StringCollection();
String[] tb_list = null;

Insert the Transfer SQL Server Object component into the package and assign name and description of the component:

Executable exec = p.Executables.Add(“STOCK:TransferSQLServerObjectsTask”);
TaskHost th = exec as TaskHost;
th.Properties[“Name”].SetValue(th, “Transfer SQL Server Objects Task – Views”);
th.Properties[“Description”].SetValue(th, “Transfer SQL Server Objects Task – Views”);

Supply the source and destination SQL Server databases:

string SourceDatabase = “AdventureWorksDW2008”;
string DestinationDatabase = “AdventureWorks”;

th.Properties[“SourceConnection”].SetValue(th, “source_conn”);
th.Properties[“SourceDatabase”].SetValue(th, SourceDatabase);
th.Properties[“DestinationConnection”].SetValue(th, “des_conn”);
th.Properties[“DestinationDatabase”].SetValue(th, DestinationDatabase);
Try not to remove existing views in destination that are similar to the object to be copied:

Boolean DropObjectsFirst = false;

The rest of the object properties must be set as follows:

Boolean CopyAllObjects = false;
Boolean IncludeExtendedProperties = false;
Boolean CopyData = true;
Boolean CopySchema = true;
Boolean UseCollation = false;
Boolean IncludeDependentObjects = false;

th.Properties[“DropObjectsFirst”].SetValue(th, DropObjectsFirst);
th.Properties[“IncludeExtendedProperties”].SetValue(th, IncludeExtendedProperties);
th.Properties[“CopyData”].SetValue(th, CopyData);
th.Properties[“CopySchema”].SetValue(th, CopySchema);
th.Properties[“UseCollation”].SetValue(th, UseCollation);
th.Properties[“IncludeDependentObjects”].SetValue(th, IncludeDependentObjects);
th.Properties[“CopyAllObjects”].SetValue(th, CopyAllObjects);
Boolean CopyAllViews = false;
Boolean Coll_CopyAllViews = true;
th.Properties[“CopyAllViews”].SetValue(th, CopyAllViews);
if (CopyAllViews == false)
if (Coll_CopyAllViews == true)
tb_list = new String[] { view_list_names };
th.Properties[“ViewsList”].SetValue(th, tb_Col);
We then save the package into a file system.
Dts.TaskResult = (int)ScriptResults.Success;
SIFISO_app.SaveToXml(“C:\\TEMP\\pkg_Exec_Pkg_Tasks_Views.dtsx”, dyna_pkg, null);
It’s that simple!
You can now execute your script task and the package will be created in location you specified.
