Property Value

One of the DataRowVersion values. The default is Current.

This property is used by the UpdateCommand during the DbDataAdapter.Update to determine whether the original or current value is used for a parameter value. This lets primary keys be updated. This property is set to the version of the DataRow used by the System.Data.DataRow.Item(System.Int32) property (DataRow indexer), or the System.Data.DataRow.GetChildRows(System.Data.DataRelation) method of the DataRow object.

The following example creates a OracleParameter and sets some of its properties.

Public Sub CreateOracleParameter()
   Dim parameter As New OracleParameter("pDName", OracleType.VarChar)
   parameter.IsNullable = True
   parameter.SourceColumn = "Description"
   parameter.SourceVersion = DataRowVersion.Current
   parameter.Direction = ParameterDirection.Output
End Sub
