Public bug reported: Binary package hint: php5-mysql
When using MySQLi and prepared statements, it seems as though some write-based queries (such as UPDATE) end up getting bad values. Specifically, items after a WHERE clause are getting values of 0 or things like \0\0 where they should be getting a proper ID (such as 123). This issue was encountered on Ubuntu 9.10 with PHP 5.2.10. This issue does not occur on Ubuntu 9.04 with PHP 5.2.6. Same version of MySQL. Same php.ini and my.cnf. To reproduce: 1. Grab files from: http://www.moocowproductions.org/tmp/test_cases/ 2. Run .SQL script through MySQL 3. Enable gereral query log in MySQL 3a. For MySQL 5.0, edit /etc/my.cnf and add 'log' and restart 3b. For MySQL 5.1, run "SET GLOBAL general_log=1" 4. Edit mysqli_bug.php and modify $dbPassword 5. Run mysqli_bug.php 6. Check General Log (See Expected and Actual results) The expected output of the MySQL general log should be something like: The MySQL general log should look like this: 61649 Query SET sql_mode='TRADITIONAL' 61649 Query set autocommit=0 61649 Prepare UPDATE t1 SET itemID = ? WHERE num1 = ? 61649 Execute UPDATE t1 SET itemID = 4 WHERE num1 = 5 61649 Close stmt 61649 Query commit 61649 Quit The actual result is: The log, instead, looks like this: 124 Query SET sql_mode='TRADITIONAL' 124 Query set autocommit=0 124 Prepare UPDATE t1 SET itemID = ? WHERE num1 = ? 124 Execute UPDATE t1 SET itemID = 4 WHERE num1 = 0 124 Close stmt 124 Query commit 124 Quit (Note that num1 = 0 and it should be 5) So far, this only appears to be happening with UPDATE queries. SELECTs do not have this problem, and neither do INSERTs. I did not run into an issue with DELETEs, though I did not test this thoroughly. ** Affects: php5 (Ubuntu) Importance: Undecided Status: New -- MySQLi Prepared Statements Not Working Correctly With UPDATEs https://bugs.launchpad.net/bugs/488600 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to php5 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
