Public Sub CreateOleDbParameter()  
    Dim parameter As New OleDbParameter("Description", OleDbType.VarChar, 88)  
    parameter.SourceColumn = "Description"  
    parameter.SourceVersion = DataRowVersion.Current  
End Sub  

public void CreateOleDbParameter()   
 {  
    OleDbParameter parameter = new OleDbParameter("Description", OleDbType.VarChar, 88);  
    parameter.SourceColumn = "Description";  
    parameter.SourceVersion = DataRowVersion.Current;  
 }

Remarks

Used by UpdateCommand during an update operation to determine whether the parameter value is set to Current or Original. This lets primary keys be updated. This property is set to the version of the DataRow used by the Item[] property, or the GetChildRows method of the DataRow object.
