'Declaration
 
Public Class DB2LoaderColumn 
   Inherits Devart.Common.DbLoaderColumn

Remarks

Each DB2Loader uses a DB2Loader.Columns to maintain a collection of DB2LoaderColumn objects. The DB2LoaderColumn object represents the attributes for column loading. Every DB2LoaderColumn object corresponds to one of the table fields with the same name as its Name property.

You can manually make changes to the DB2Loader.Columns collection to exclude some columns from INSERT statement generated by DB2Loader object.

Example

This sample shows how to perform loading of data into a table with the last column set to default value.

csharp

public void LoadData(DB2Connection db2Connection)
{
  db2Connection.Open();
  DB2Loader loader = new DB2Loader();
  loader.Connection = db2Connection;
  loader.TableName = "load_table";
  try
  {
    loader.CreateColumns();
    //Do not insert data in the last column
    loader.Columns.RemoveAt(loader.Columns.Count-1);
    loader.Open();
    for (int i = 1; i <= 100; i++)
    {
      loader.SetValue("id", i);
      loader.SetValue(1, "test string");
      loader.SetValue("date_field", DateTime.Now);
      loader.NextRow();
    }
    loader.Close();
  }
  finally
  {
    db2Connection.Close();
  }
}

Visual Basic

Public Sub LoadData(ByVal db2Connection As DB2Connection)
  db2Connection.Open()
  Dim loader As DB2Loader
  loader = New DB2Loader
  loader.Connection = db2Connection
  loader.TableName = "load_table"
  Try
    loader.CreateColumns()
    ' Do not insert data in the last column
    loader.Columns.RemoveAt(loader.Columns.Count - 1)
    loader.Open()
    Dim i As Integer
    For i = 1 To 100
      loader.SetValue("id", i)
      loader.SetValue(1, "test string")
      loader.SetValue("date_field", DateTime.Now)
      loader.NextRow()
    Next i
    loader.Close()
  Finally
    db2Connection.Close()
  End Try
End Sub
