Public Function Add ( _
          src As String, _
          dest As Integer _
) As DB2BulkCopyColumnMapping
[C#]
public DB2BulkCopyColumnMapping Add(
         string src,
         int dest
)
[C++]
public:
DB2BulkCopyColumnMapping* Add (
         String* src,
         int dest
)
[JScript]
public function Add (
          src : String,
          dest : int
) : DB2BulkCopyColumnMapping

Parameters

src: Name of the column being copied from the data source.
dest: Ordinal value of the column being mapped in the destination table.

Return value

The column mapping added to the DB2BulkCopyColumnMappingCollection.

Example

[C#] The following example demonstrates a bulk copy of data from a DB2DataReader into the DEPARTMENT table. The column mappings between the source and target tables are defined by a DB2BulkCopyColumnMappingCollection instance.

[C#]
public static void copyIntoSales(DB2Connection conn, DB2DataReader reader)
{
  DB2BulkCopy salesCopy = new DB2BulkCopy(conn);
  salesCopy.DestinationTableName = "DEPARTMENT";

  DB2BulkCopyColumnMappingCollection colMapCollection;
  colMapCollection = new DB2BulkCopyColumnMappingCollection();

  salesCopy.ColumnMappings = colMapCollection;

  colMapCollection.Add("DEPTNUMB", 0);
  colMapCollection.Add("DEPTNAME", 1);
  colMapCollection.Add("MANAGER", 3);
  colMapCollection.Add("LOCATION", 4);

  try
  {
    salesCopy.WriteToServer(reader);
    salesCopy.Close();
  }
  catch (DB2Exception ex)
  {
    MessageBox.Show(ex.ToString(), "Exception");
  }
}
