Description:
------------
The functions odbc_field_len(), odbc_field_precision(), odbc_field_scale() - don't work corractly when use Transbace ODBC driver in "SELECT ..." SQL-statement.

Reproduce code:
---------------
$con_str = "Driver={Transbase ODBC};Database=MyDB";
$db_conn = odbc_connect($con_str,"user","0")

$query = "SELECT * FROM Tab1";
$res = odbc_exec($db_conn, $query);
$num_fields = odbc_num_fields($res);
for($j=1; $j<=$num_fields; $j++){
  echo odbc_field_name($res,$j);
  echo '<br/>' . odbc_field_type($res,$j);
  echo '<br/>' . odbc_field_len($res,$j);
  echo '<br/>' . odbc_field_precision($res,$j);
  echo '<br/>' . odbc_field_scale($res,$j);
  echo '<br/>' . odbc_result($res,$j);
}

odbc_free_result($res);    // Free Result
odbc_close($db_conn);    // Close Connection

Expected result:
----------------
