DB2®BulkCopyColumnMapping.DB2BulkCopyColumnMapping(string, int) Constructor

Initializes a new DB2BulkCopyColumnMapping object using a column name for the data source column and a column ordinal for the destination column.

Namespace:: IBM.Data.DB2
Assembly:: IBM.Data.DB2 (in IBM.Data.DB2.dll)

Syntax


[Visual Basic]
Public Sub New ( _
  source As String, _
  destination As Integer _
)
[C#]
public DB2BulkCopyColumnMapping(
  string source
  int destination
);
[C++]
public: DB2BulkCopyColumnMapping(
  String* source
  int destination
);
[JScript]
public function DB2BulkCopyColumnMapping(
  source : String,
  destination : int
)

Parameters

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

Remarks

For case sensitivity to be maintained, the column name must be enclosed within an extra set of double-quotes. For example, the source column can be set as follows:


DB2BulkCopyColumnMapping colMapDeptNum = 
new DB2BulkCopyColumnMapping("\"LoCaTion\"", 0);

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 in DB2BulkCopyColumnMapping instances.

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

  DB2BulkCopyColumnMapping colMapDeptNum = 
  new DB2BulkCopyColumnMapping("\"DEPTNUMB\"", 0);
  DB2BulkCopyColumnMapping colMapDeptNme = 
  new DB2BulkCopyColumnMapping("\"DEPTNAME\"", 1);
  DB2BulkCopyColumnMapping colMapDeptMgr = 
  new DB2BulkCopyColumnMapping("\"MANAGER\"", 3);
  DB2BulkCopyColumnMapping colMapDeptLoc = 
  new DB2BulkCopyColumnMapping("\"LOCATION\"", 4);
 
  salesCopy.ColumnMappings.Add(colMapDeptNum);
  salesCopy.ColumnMappings.Add(colMapDeptNme);
  salesCopy.ColumnMappings.Add(colMapDeptMgr);
  salesCopy.ColumnMappings.Add(colMapDeptLoc);

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