#38389 [NEW]: What is the default type of bindParam(), bindValue() and execute(array) ? (PDO)

From: baldurien at bbnwn dot eu Operating system: Irrelevant PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: What is the default type of bindParam(), bindValue() and execute(array) ? (PDO) Description: ------------ I was wondering what is the default type of parameter when none is set? Reproduce code: --------------- If I run that code : $dbh = new PDO( 'mysql:host=localhost;dbname=xxx', 'xxx', 'xxx'); $stmt = $dbh->prepare('SELECT ? FROM DUAL WHERE 1 = ?'); var_dump($stmt->execute(array('aa\'aa', 'aaa'))); This dump true, meaning that 'aaa' was casted to a string and that the actual query looks like this in mySQL : SELECT 'aa''aa' FROM DUAL WHERE 1 = 'aaa' Expected result: ---------------- The documentation should indicate that when no type is provided (while calling bindParam(), bindValue(), or execute()), PDO::PARAM_STRING is used. Actual result: -------------- Neither bindParam(), bindValue() or execute() speak of a default type, nor the main page of PDO (http://fr.php.net/manual/en/ref.pdo.php) describe it. Thus, we could expect anything from the driver (like casting variable into integer instead of string). -- Edit bug report at http://bugs.php.net/?id=38389&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=38389&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=38389&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=38389&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=38389&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=38389&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=38389&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=38389&r=needscript Try newer version: http://bugs.php.net/fix.php?id=38389&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=38389&r=support Expected behavior: http://bugs.php.net/fix.php?id=38389&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=38389&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=38389&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=38389&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=38389&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=38389&r=dst IIS Stability: http://bugs.php.net/fix.php?id=38389&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=38389&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=38389&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=38389&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=38389&r=mysqlcfg
