From: mckameh2 at armadillo dot fr Operating system: Vista PHP version: 5.2.6 PHP Bug Type: PDO related Bug description: bindValue does not use data_type parameter correctly
Description: ------------ The function odbc_stmt_param_hook() in pdo_odbc\odbc_stmt.c does not use the data_type parameter correctly if the call to SQLDescribeParam()does not succeed. Instead of converting in this case the data_type parameter from PDO:PARAM_* to the matching SQL type, it sets in most cases the SQL type to SQL_LONGVARCHAR. Remark: The data_type parameter should IMHO have absolute priority over SQLDescribeParam(). In effect, if the data_type parameter is specified, than there is no point in even calling SQLDescribeParam(). Especially since the ODBC database server may not be able to assign a correct data-type to the place-holder ('?'). Reproduce code: --------------- gDBObject = new PDO('odbc:DATABASE', '', ''); $x = 1; $lvStmt = $gDBObject->prepare('SELECT col1 FROM Table WHERE col2 = ?'); $lvStmt->bindValue(1,$x, PDO::PARAM_INT); $lvStmt->execute(); But you do need to use an ODBC database that will not return in this case a SQL_SUCCESS return-value for SQLDescribeParam() ! Expected result: ---------------- I would expect the following request to be sent to the ODBC database server: SELECT col1 FROM Table WHERE col2 = 1 Actual result: -------------- The following request is sent to the ODBC database server: SELECT col1 FROM Table WHERE col2 = '1' which is a syntax error, since col2 is integer. -- Edit bug report at http://bugs.php.net/?id=46523&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46523&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46523&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46523&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46523&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=46523&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=46523&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46523&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46523&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46523&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46523&r=support Expected behavior: http://bugs.php.net/fix.php?id=46523&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46523&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46523&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46523&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46523&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46523&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46523&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46523&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46523&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46523&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46523&r=mysqlcfg
