Bug #10155 Updated: Insert or update query not functioning correctly

ID: 10155 Updated by: stupidscript@hotmail.com Reported By: jules@bj-design.co.uk Status: Closed Bug Type: ODBC related Operating System: Windows NT 4.0 build 1381 PHP Version: 4.0.4pl1 New Comment: I am having the same or very similar problem: (There's a bunch more code involved, of course, so I'm just including relevant examples, below.) <-------- START EXAMPLE -------> <...appropriate persistent db access info...> <...data-to-variable assignments...> mysql_db_query("dbX","update tableX set col1='$data1' where ID='$id'"); <...error-reporting code...> echo mysql_affected_rows(); <------ END EXAMPLE ------> Result: no affected rows, no errors, and no update I tried adding a SELECT statement immediately following the UPDATE statement, per this bug report's suggestion: Result: 1 affected row, no errors, and no update So PHP thought 1 row had been updated...but it had not been. This is a piece of script that we have been using successfully for about 4 months, but it started to malfunction about 3 weeks ago. INSERT, and DELETE statements work fine. Version Info/Configuration: FreeBSD 4.4 Release i386 PHP v. 4.1.2 (same problem with 4.0.6, by the way...) Apache/1.3.12 OpenSSL/0.9.6a MySQL v. 3.23.44 Thanks.

Put simply the update, insert and, possibly, delete querys all appear to work perfectely with no errors reported, except that the database ends up being unchanged afterwards. The only way I have been able to fix this is to query the same table with a select before the end of the script, the changes are then implemented. I have played with autocommit and commit with no effect so I figure it must be a bug in either PHP or the ODBC drivers. Here is one of the scripts with a totally unecessary select towards the end to make it work. <html> <head> <? /* Site by Just Biz http://www.justbiz.co.uk ida@justbiz.co.uk + 44 (0)870 841 3040 Project: Space Windows Routine: ModifySeries2.php Created: 23/03/01 Descrip: Modify series number, title and description, update database.
