#41244 [NEW]: Multiple Queries in MSSQL Kills Connection and Prevents New Connections

From: mallinger at tc dot edu Operating system: Windows 2003 Server PHP version: 5.2.1 PHP Bug Type: MSSQL related Bug description: Multiple Queries in MSSQL Kills Connection and Prevents New Connections Description: ------------ When executing multiple queries from a single mssql_query call, the connection is lost and subsequent connections cannot be created. There are similar problems documented for PHP4, but it seems that (a) this is not documented for PHP5; and (b) the inability to create subsequent connections is not documented. In particular, it seems the mssql_select_db is what is failing in the second connection. Reproduce code: --------------- $conn = mssql_connect('host', 'user', 'pass'); mssql_select_db("db", $conn); mssql_query("QUERY 1", $conn); mssql_query("QUERY 2; QUERY 3; QUERY 4;", $conn); // this will fail: mssql_query("QUERY 5", $conn); // this is ok mssql_close($conn); // everything below will fail too: $conn2 = mssql_connect('host', 'user', 'pass'); mssql_select_db("db", $conn2); mssql_query("QUERY 6", $conn2); Expected result: ---------------- The queries should execute with no problems. Actual result: -------------- Everything after the multiple query mssql_query call ("QUERY 2; QUERY 3; QUERY 4;" will fail. New connections fail when trying to select a database ("mssql_select_db() [function.mssql-select-db]: Unable to select database:...") and the existing connection cannot be used anymore ("mssql_query() [function.mssql-query]: Query failed in...") . -- Edit bug report at http://bugs.php.net/?id=41244&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41244&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41244&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41244&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41244&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41244&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41244&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41244&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41244&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41244&r=support Expected behavior: http://bugs.php.net/fix.php?id=41244&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41244&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41244&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41244&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41244&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41244&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41244&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41244&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41244&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41244&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41244&r=mysqlcfg
