DB2®BulkCopyColumnMapping Class

Inheritance hierarchy

Syntax

[Visual Basic]
NotInheritable Public Class DB2BulkCopyColumnMapping
[C#]
public sealed class DB2BulkCopyColumnMapping
[C++]
public __gc __sealed class DB2BulkCopyColumnMapping
[JScript]
public final class DB2BulkCopyColumnMapping

Remarks

If no column mappings are defined, columns are mapped based on their ordinal positions in their respective table schema. If the source and target columns are not compatible, an InvalidOperationException is thrown.

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 DB2BulkCopyColumnMapping instances.

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

  DB2BulkCopyColumnMapping colMapDeptNum = 
  new DB2BulkCopyColumnMapping("DEPTNUMB", "DEPTNO");
  DB2BulkCopyColumnMapping colMapDeptNme = 
  new DB2BulkCopyColumnMapping("DEPTNAME", "DEPTNAME");
  DB2BulkCopyColumnMapping colMapDeptMgr = 
  new DB2BulkCopyColumnMapping("MANAGER", "ADMRDEPT");
  DB2BulkCopyColumnMapping colMapDeptLoc = 
  new DB2BulkCopyColumnMapping("LOCATION", "LOCATION");

  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");
  }
}
