This property is used by the UpdateCommand during the Update to determine whether the original or current value is used for a parameter value. This allows primary keys to be updated. This property is ignored by the InsertCommand and DeleteCommand. This property is set to the version of the DataRow used by the Item property, or the GetChildRows method of the DataRow object.

The following example creates an instance of the implementing class, SqlParameter, and sets some of its properties.

public void CreateSqlParameter() 
{
    SqlParameter parameter = new SqlParameter(
        "@Description", SqlDbType.VarChar);
    parameter.IsNullable = true;
    parameter.SourceColumn = "Description";
    parameter.SourceVersion = DataRowVersion.Current;
    parameter.Direction = ParameterDirection.Output;
