From: freetds228 at lewenberg dot com Operating system: RedHat Enterprise Linux 3 PHP version: 4.4.1 PHP Bug Type: MSSQL related Bug description: MSSQL query fails when retrieving date field
Description: ------------ When running a simple SELECT select query against an MS SQL server, if the result set has a field with a non-NULL date, we are getting the following error (with --enable-debug flag on): [Sat Nov 5 11:26:07 2005] Script: '/www-s/testfreetds.php' --------------------------------------- /root/tmp/php-4.4.1/ext/mssql/php_mssql.c(191) : Block 0x093CA2E0 status: /root/tmp/php-4.4.1/Zend/zend_variables.c(44) : Actual location (location was relayed) Beginning: OK (allocated on /root/tmp/php-4.4.1/ext/mssql/php_mssql.c:904, 19 bytes) End: Overflown (magic=0x31383A34 instead of 0x2A8FCC84) At least 4 bytes overflown --------------------------------------- The query returns only a single row and field (a date). Note that Perl running the same query using the same freetds libraries has no errors. We have compiled 4.4.1 against freetds 0.63 using the --with-mssql option. Reproduce code: --------------- $db = mssql_connect('mssqlserver', 'user', 'secret') ; $rs = mssql_query('SELECT DateLastModified FROM Table WHERE rid = 1', $db) ; Expected result: ---------------- The date should be accessible in the result set. Actual result: -------------- [Sat Nov 5 11:26:07 2005] Script: '/www-s/testfreetds.php' --------------------------------------- /root/tmp/php-4.4.1/ext/mssql/php_mssql.c(191) : Block 0x093CA2E0 status: /root/tmp/php-4.4.1/Zend/zend_variables.c(44) : Actual location (location was relayed) Beginning: OK (allocated on /root/tmp/php-4.4.1/ext/mssql/php_mssql.c:904, 19 bytes) End: Overflown (magic=0x31383A34 instead of 0x2A8FCC84) At least 4 bytes overflown --------------------------------------- -- Edit bug report at http://bugs.php.net/?id=35115&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=35115&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=35115&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=35115&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=35115&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=35115&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=35115&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=35115&r=needscript Try newer version: http://bugs.php.net/fix.php?id=35115&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=35115&r=support Expected behavior: http://bugs.php.net/fix.php?id=35115&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=35115&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=35115&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=35115&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=35115&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=35115&r=dst IIS Stability: http://bugs.php.net/fix.php?id=35115&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=35115&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=35115&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=35115&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=35115&r=mysqlcfg
