PDO with prepared statements

i'm using PHP 5.1.2, and trying to manipulatre a database with PDO_ODBC accessing a MS SQL Server database. i can execute normal queries with no problem. but when i start executing prepared statements i run into problems. has anyone successfully used multiple parameter prepared statements with MSSQL and PDO? one thing that would help is if i could get the full text of whatever PDO is trying to send to SQL Server, does anyone know of a way to get that? i set up a test table zTestTable, with a TestID autoincrement primary key int, a Test (nvarchar(200)) and a TestNumber(int). when i execute the following code, it inserts a row with the value 1 for Test and TestNumber. the same thing happens if i try to use ? parameters instead of named parameters. $oConnection = new PDO($sDSN); $sSQL = 'INSERT INTO zTest_TBL (Test, TestNumber) VALUES (:Test, :TestNumber) '; $oStatement = $oConnection->prepare($sSQL); $s='test insert string passing an array to execute'; $i=1; $oStatement->execute(array(':Test'=>$s,':TestNumber'=>$i)); print_r($oStatement->errorInfo()); the second bit of code is an attempt to bind parameters and run the same insert. this one inserts a row with NULLs for Test and TestNumber. $oConnection = new PDO($sDSN); $sSQL = 'INSERT INTO zTest_TBL (Test, TestNumber) VALUES (:Test, :TestNumber) '; print $sSQL; $oStatement = $oConnection->prepare($sSQL); $s2='test insert string binding a parameter'; $oStatement->bindParam(':Test', $s2, PDO::PARAM_STR); $oStatement->bindParam('TestNumber', $i, PDO::PARAM_INT); $oStatement->execute(); thanks in advance, --travis
