#49643 [NEW]: Improper quoting on datetime bound parameters for postgresql

From: alandsidel at dnsstuff dot com Operating system: FreeBSD PHP version: 5.3.0 PHP Bug Type: PDO related Bug description: Improper quoting on datetime bound parameters for postgresql Description: ------------ Running PostGreSQL 8.4, given a simple table like: When using a bound parameter in prepare (named or unnamed) to a timestamp field, the parameter is improperly quoted resulting in errors on INSERT or UPDATE statements that are using expressions rather than simple datetime strings. Reproduce code: --------------- // In the postgresql database CREATE TABLE foo ( id SERIAL UNIQUE NOT NULL, dtSometime TIMESTAMP WITH TIME ZONE NOT NULL ); // Assuming $dbh is a connection to the above database if ($stmt = $dbh->prepare('INSERT INTO foo (dtSometime) VALUES (:dtsometime)') { if ($stmt->execute(array('now() + interval \'1 year\'')) { print("ok!\n"); } else { print_r($dbh->errorInfo()); } } Expected result: ---------------- Expect a row to be inserted and 'ok!' to print. Actual result: -------------- The following is printed on the console: //--cut ( [0] => 00000 [1] => 7 [2] => ERROR: invalid input syntax for type timestamp with time zone: "now() + interval '1 year'" ) //--cut A direct insert with the given SQL works fine as expected, so this must be a quoting issue that is forcing postgresql to interpret the expression as a literal datetime. -- Edit bug report at http://bugs.php.net/?id=49643&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=49643&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=49643&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=49643&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=49643&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=49643&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=49643&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=49643&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=49643&r=needscript Try newer version: http://bugs.php.net/fix.php?id=49643&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=49643&r=support Expected behavior: http://bugs.php.net/fix.php?id=49643&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=49643&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=49643&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=49643&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=49643&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=49643&r=dst IIS Stability: http://bugs.php.net/fix.php?id=49643&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=49643&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=49643&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=49643&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=49643&r=mysqlcfg
