Description: ------------ Hello all I'm expiriencing a bug when trying to perform something like this MySQL query from PHP: Select *, @d := x^2 from o where cos(@d)+sin(@d)>0; this is a short version of my real query, but shows the deal. (x is a key in o and the important part is the repeated use of @d, this is what I want since it is a more complex calculation in "real life".) When I test it from the prompt in MySQL it works just fine and gives the results as expected. But from a PHP script it returns 0 rows...! I'm certain that something is wrong because when I use a version that looks like this: WHERE cos(x^2)+sin(x^2)>0 - that is @d substituted in place - it work just fine. Can anyone explain this ? Thanks in advance. -- Edit bug report at http://bugs.php.net/?id=30883&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30883&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30883&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30883&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30883&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30883&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30883&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30883&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30883&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30883&r=support Expected behavior: http://bugs.php.net/fix.php?id=30883&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30883&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30883&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30883&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30883&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30883&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30883&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30883&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30883&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30883&r=mysqlcfg
