Hi,
I'm trying to create a SSIS package. I have used OLEDBSource adapter to get the source table's data and transferring the data to an OLEDBDestination adapter. I tried but I'm facing the problem in mapping the metadata contents.
My code:
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
static void Main(string[] args)
{
// Create a new package
Package package = new Package();
package.Name = "OLE DB Transfer";
// Add a Data Flow task
TaskHost taskHost = package.Executables.Add("DTS.Pipeline") as TaskHost;
taskHost.Name = "Transfer Table";
IDTSPipeline90 pipeline = taskHost.InnerObject as MainPipe;
// Get the pipeline's component metadata collection
IDTSComponentMetaDataCollection90 componentMetadataCollection = pipeline.ComponentMetaDataCollection;
// Add a new component metadata object to the data flow
IDTSComponentMetaData90 oledbSourceMetadata = componentMetadataCollection.New();
// Associate the component metadata object with the OLE DB Source Adapter
oledbSourceMetadata.ComponentClassID = "DTSAdapter.OLEDBSource";
// Instantiate the OLE DB Source adapter
IDTSDesigntimeComponent90 oledbSourceComponent = oledbSourceMetadata.Instantiate();
// Ask the component to set up its component metadata object
oledbSourceComponent.ProvideComponentProperties();
// Add an OLE DB connection manager
ConnectionManager connectionManagerSource = package.Connections.Add("OLEDB");
connectionManagerSource.Name = "OLEDBSource";
// Set the connection string
connectionManagerSource.ConnectionString = "provider=sqlncli;server=HSCHBSCGN25008;integrated security=sspi;database=Muthu_SSIS_Testing";
// Set the connection manager as the OLE DB Source adapter's runtime connection
IDTSRuntimeConnection90 runtimeConnectionSource = oledbSourceMetadata.RuntimeConnectionCollection["OleDbConnection"];
runtimeConnectionSource.ConnectionManagerID = connectionManagerSource.ID;
// Tell the OLE DB Source adapter to use the SQL Command access mode.
oledbSourceComponent.SetComponentProperty("AccessMode", 2);
// Set up the SQL command
oledbSourceComponent.SetComponentProperty("SqlCommand", "select * from EmployeeTable");
// Set up the connection manager object
runtimeConnectionSource.ConnectionManager = DtsConvert.ToConnectionManager90(connectionManagerSource);
// Establish the database connection
oledbSourceComponent.AcquireConnections(null);
// Set up the column metadata
oledbSourceComponent.ReinitializeMetaData();
// Release the database connection
oledbSourceComponent.ReleaseConnections();
// Release the connection manager
runtimeConnectionSource.ReleaseConnectionManager();
// Add a new component metadata object to the data flow
IDTSComponentMetaData90 oledbDestinationMetadata = componentMetadataCollection.New();
//Associate the component metadata object with the OLE DB Destination Adapter
oledbDestinationMetadata.ComponentClassID = "DTSAdapter.OLEDBDestination";
// Instantiate the OLE DB Destination adapter
IDTSDesigntimeComponent90 oledbDestinationComponent = oledbDestinationMetadata.Instantiate();
// Ask the component to set up its component metadata object
oledbDestinationComponent.ProvideComponentProperties();
// Add an OLE DB connection manager
ConnectionManager connectionManagerDestination = package.Connections.Add("OLEDB");
connectionManagerDestination.Name = "OLEDBDestination";
// Set the connection string
connectionManagerDestination.ConnectionString = "provider=sqlncli;server=HSCHBSCGN25008;integrated security=sspi;database=Muthu_SSIS_Testing";
// Set the connection manager as the OLE DB Destination adapter's runtime connection
IDTSRuntimeConnection90 runtimeConnectionDestination = oledbDestinationMetadata.RuntimeConnectionCollection["OleDbConnection"];
runtimeConnectionDestination.ConnectionManagerID = connectionManagerDestination.ID;
// Tell the OLE DB Destination adapter to use the SQL Command access mode.
oledbDestinationComponent.SetComponentProperty("AccessMode", 2);
// Set up the SQL command
oledbDestinationComponent.SetComponentProperty("SqlCommand", "select from EmplTable");
// Set up the connection manager object
runtimeConnectionDestination.ConnectionManager = DtsConvert.ToConnectionManager90(connectionManagerDestination);
// Get the standard output of the OLE DB Source adapter
IDTSOutput90 oledbSourceOutput = oledbSourceMetadata.OutputCollection["OLE DB Source Output"];
// Get the input of the OLE DB Destination adapter
IDTSInput90 oledbDestinationInput = oledbDestinationMetadata.InputCollection["OLE DB Destination Input"];
// Create a new path object
IDTSPath90 path = pipeline.PathCollection.New();
// Connect the source and destination adapters
path.AttachPathAndPropagateNotifications(oledbSourceOutput, oledbDestinationInput);
IDTSInput90 input = oledbDestinationInput;
IDTSVirtualInput90 vInput = input.GetVirtualInput();
foreach (IDTSVirtualInputColumn90 vColumn in vInput.VirtualInputColumnCollection)
{
// Call the SetUsageType method of the destination
// to add each available virtual input column as an input column.
oledbDestinationComponent.SetUsageType(
input.ID, vInput, vColumn.LineageID, DTSUsageType.UT_READONLY);
}
foreach (IDTSInputColumn90 col in oledbDestinationInput.InputColumnCollection)
{
IDTSExternalMetadataColumn90 exCol = oledbDestinationInput.ExternalMetadataColumnCollection[col.Name];
oledbDestinationComponent.MapInputColumn(oledbDestinationInput.ID, col.ID, exCol.ID);
}
Console.WriteLine("done");
Console.ReadKey();
// Save the package
//Application application = new Application();
//application.SaveToXml(@."c:\OLEDBTransfer.dtsx", package, null);
}
While debugging, I'm getting exception (ELEMENTNOTFOUND) at this line
IDTSExternalMetadataColumn90 exCol = oledbDestinationInput.ExternalMetadataColumnCollection[col.Name];
because metadata have no appropriate column to map with the destination component.
Any one help me to resolve this issue.

Hi,
I have resolved my issues.
For destination component, I initialized the connection and reinitialized metadata and done the mapping then released the connection for destination component.
Now my code is working.
Thanks for your helps..

|||If it is a bug, it is one common to all VS products, and has been since VS .Net came out. The IDE will always create files on disk first. You must supply the filename upfront for a solution, project or file, although in the later case in can be inferred as it is here. I'd rather it save it for me, than me forget and loose work. VS will also save the package every time you execute it as well.|||Daran, thanks.
