Interbase DB, again =)

Following up on the thread on DB_FETCHMODE_ASSOC and Interbase, which was fixed by Tomas a few weeks ago, I am a bit unsure on the functionality of the fix. The following code (ibase.php 153-154): if ($fetchmode & DB_FETCHMODE_ASSOC) { $ar = get_object_vars(ibase_fetch_object($result)); ignores empty or null fields, therefore on a multi-rows result set, the number of fields returned varies from row to row. Clearly this is not a good behaviour for a db driver =) I tried a few quick fixes, mainly by storing the field names and re-creating an associative array from ibase_fetch_row (ugly, I know), but I keep getting Interbase synchronization errors, which were already discussed in the previous thread. Any suggestions? Ludo
