From: yury at nix dot co dot il Operating system: FreeBSD 7.2-STABLE PHP version: 5.2.11 PHP Bug Type: PDO related Bug description: multiple statments result exception
Description: ------------ When using multiple statments in a single $pdo->execute(), php throws an exception, however the staments bieng executed anyway. ( example: http://pastebin.com/f6aec645c ) I think the mysql server expects the resultset to be advanced even if it's empty, as shown in the c-api example here: http://dev.mysql.com/doc/refman/5.1/en/c-api-multiple-queries.html I think the follwing will resolve the issue ( diff against svn 5_2 ) *** mysql_driver.c Sat Nov 28 13:13:07 2009 --- /home/yury/php-5.2.11/ext/pdo_mysql/mysql_driver.c Fri Nov 27 13:55:46 2009 *************** *** 252,261 **** --- 252,262 ---- my_ulonglong c = mysql_affected_rows(H->server); if (c == (my_ulonglong) -1) { pdo_mysql_error(dbh); return (H->einfo.errcode ? -1 : 0); } else { + while ( 0 == mysql_next_result( H->server ) ); return c; } } } Reproduce code: --------------- http://pastebin.com/f6aec645c Expected result: ---------------- throw exception and not commit -or- commit and not throw exception Actual result: -------------- The follwing exception thrown: SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute. But the data IS commited to the database. -- Edit bug report at http://bugs.php.net/?id=50318&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50318&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50318&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50318&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50318&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50318&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50318&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50318&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50318&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50318&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50318&r=support Expected behavior: http://bugs.php.net/fix.php?id=50318&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50318&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50318&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50318&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50318&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50318&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50318&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50318&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50318&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50318&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50318&r=mysqlcfg
