the PEAR ODBC driver uses odbc_fetch_into() which doesn't handle LONG data types.
read() sets odbc_longreadlen() which determines how to handle LONG values and
then users odbc_result() to fetch the value.

So if the PEAR ODBC driver was fixed then this could be removed, but not all
ODBC databases can return the needed infomation about the field types. A PEAR
SAPDB driver could be a possibility, i guess.
