-/**
- * TDbDataReader represents a forward-only stream of rows from a query result set.
- *
- * To read the current row of data, call {@link read}. The method {@link readAll}
- * returns all the rows in a single array.
- *
- * One can also retrieve the rows of data in TDbDataReader by using foreach:
- * <pre>
- * foreach($reader as $row)
- * // $row represents a row of data
- * </pre>
- * Since TDbDataReader is a forward-only stream, you can only traverse it once.
- *
- * It is possible to use a specific mode of data fetching by setting
- * {@link setFetchMode FetchMode}. See {@link http://www.php.net/manual/en/function.PDOStatement-setFetchMode.php}
- * for more details.
