Edit report at http://bugs.php.net/bug.php?id=53007&edit=1 ID: 53007 User updated by: crewone at gmail dot com Reported by: crewone at gmail dot com Summary: crash when result set contains NULL Status: Bogus Type: Bug Package: ODBC related Operating System: ubuntu 10.4 amd64 PHP Version: 5.3.3 Block user comment: N New Comment: Weird that nobody seems to fix this, even though the fix is simple and available. Previous Comments: ------------------------------------------------------------------------ [2010-10-30 00:53:57] lindoja at juno dot com I've also experienced ODBC crashing PHP when the result set contains a Null (and sometimes even when it does not). This occurs when accessing NUMBER fields in a Pervasive database via an ODBC DSN. The workaround I found is to add zero or an empty string to the start of the results rather than returning them directly. i.e. instead of 'Select "MyNumber","MyString" FROM "MyTable"', you'd do this: 'Select 0 + "MyNumber" As "MyNumber", '' + "MyString" As "MyString" FROM "MyTable"' ------------------------------------------------------------------------ [2010-10-07 02:26:15] felipe@php.net Duplicated of bug #52554 ------------------------------------------------------------------------ [2010-10-07 02:06:10] crewone at gmail dot com Description: ------------ PHP (CLI) crashes (Segfault) on a NULL in the result set. - latest easysoft odbc-odbc bridge and unixODBC-2.3.0 (compiled from source) - php-5.3.3 compiled from source (--with-unixODBC) Database is a PROGRESS OPENEDGE 10.1C database.
