I have a main_includes.php which include_once/require_once all needed things like MDB2.php or setpath for /pear folder Anyway, you are right. issue is on the Query command. Here is the error message : MDB2 Error: unknown error _doQuery: [Error message: Could not execute statement] [Last executed query: SELECT * FROM articles] but it does not help me so much this error. Ok, it can not execute the query but why ? example if from the PEAR help file :-( Al. On 11/11/06, Mark Wiesemann <[EMAIL PROTECTED]> wrote:

'<br />' . $res->getDebugInfo()); } It's very likely that the following error about fetchRow() is caused because the query failed: fetchRow() would then be called on an MDB2_Error (or PEAR_Error) object which, of course, does not have a fetchRow() method. > while ($row = $res->fetchRow(MDB2_FETCHMODE_ASSOC)) > { > echo $row['title'] .
