Previous Comments: ------------------------------------------------------------------------ [2009-04-29 14:13:50] steil at zweitwerk dot com Testing on Linux, I can find no improvement. The error message and result are as before ------------------------------------------------------------------------ [2009-04-25 15:07:27] jani@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://windows.php.net/snapshots/ ------------------------------------------------------------------------ [2008-05-19 16:30:10] steil at zweitwerk dot com Sorry, I thought I could straighten the example by omitting records with small content, but the long column does not support the length property whence the statement should just read $res = $db->query("SELECT longcolumn FROM table"); However, the bug remains. ------------------------------------------------------------------------ [2008-05-16 14:43:10] steil at zweitwerk dot com Description: ------------ If you fetch from an Oracle column of datatype long, and the actual data is more than 512 byte long it will be truncated and the following warning will be issued "Warning: PDOStatement::fetch(): column 0 data was too large for buffer and was truncated to fit it in" Reproduce code: --------------- $db = new PDO('oci:dbname=...', 'user', 'pwd'); $res = $db->query("SELECT longcolumn FROM table WHERE length(longcolumn) > 512"); $row = $res->fetch(); print_r('data length: '. strlen($row[0])); results in $row[0] being truncated and the output data length: 512 Expected result: ---------------- $row[0] should contain all of the data and the output data length: x (where x > 512) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=45021&edit=1
