ID: 29324 Updated by: wez@php.net Reported By: groenink at xs4all dot nl Status: Open Bug Type: ODBC related Operating System: Windows XP PHP Version: 5.0.0 New Comment: I know this is side-stepping the issue slightly, but would you mind testing the PDO? For a bit more info: http://netevil.org/node.php?uuid=bf0a58d7-68ab-49d0-9a29-f5ec97c5dfde You'll need: http://snaps.php.net/win32/PECL_5_0/php_pdo.dll http://snaps.php.net/win32/PECL_5_0/php_pdo_odbc.dll Please reply directly to me (wez@php.net) with feedback on PDO.

(2) Getting one row with odbc_fetch_array() is fine, but as soon as you ask for the second one, the web server complains about an access violation (both Apache and IIS). Apparently the driver does something that the ODBC library in PHP doesn't expect, but most other windows programs think is fine. The problem exists in PHP 4.3.7 as well as PHP 5.0.0. Reproduce code: --------------- $db = odbc_connect("nexusdb", "", ""); // Don't use "select *", it will crash immediately. // This is something the other ODBC tools seem to // know and deal with as well. // $result = odbc_exec($db, "SELECT id, name FROM table"); $num_records_fetched = 0; $num_records_to_fetch = 2; while ($row = odbc_fetch_array($result)) { $num_records_fetched++; echo "Row {$num_records_fetched}:"; foreach ($row as $key => $value) { echo " {$key} => {$value}"; } if ($num_records_fetched >= $num_records_to_fetch) { break; } } Expected result: ---------------- I'd expect to see: row 1: id => 0001 name => foo row 2: id => 0002 name => bar Actual result: -------------- I get an "access violation". If I change "num_records_to_fetch" to 1, it no longer violates access, but I see this instead: row 1: 0001 => 0001 foo => foo ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29324&edit=1
