The rowCount method does not seem to work with pdo_sqlite, maybe because it will not support forward-only cursors: <?php error_reporting(E_ALL+E_NOTICE); $dsn = 'sqlite::memory:'; $pdo = new PDO($dsn); $pdo->exec('CREATE TABLE foo(id varchar(11) NOT NULL, PRIMARY KEY(id))'); $pdo->exec("INSERT INTO foo(id) VALUES ('ffs')"); $sqlGet = 'SELECT * FROM foo WHERE id=:id'; $stmt = $pdo->prepare($sqlGet); $id = 'ffs'; $stmt->bindParam(':id', $id, PDO::PARAM_STR); $stmt->execute(); var_dump($stmt->rowCount(), count($stmt->fetchAll())); ?> which outputs: 0 1 http://php.net/manual/en/function.sqlite-num-rows.php says sqlite_num_rows() cannot be used on unbuffered results; the explanation to the failure of the rowCount() method is probably along the same lines. The workaround would be to use the count() function on a fetched result, but it might not be as efficient. ---- Server IP: 194.246.101.61 Probable Submitter: 82.255.112.223 ---- Manual Page -- http://www.php.net/manual/en/function.PDOStatement-rowCount.php Edit -- https://master.php.net/note/edit/80041 Del: integrated -- https://master.php.net/note/delete/80041/integrated Del: useless -- https://master.php.net/note/delete/80041/useless Del: bad code -- https://master.php.net/note/delete/80041/bad+code Del: spam -- https://master.php.net/note/delete/80041/spam Del: non-english -- https://master.php.net/note/delete/80041/non-english Del: in docs -- https://master.php.net/note/delete/80041/in+docs Del: other reasons-- https://master.php.net/note/delete/80041 Reject -- https://master.php.net/note/reject/80041 Search -- https://master.php.net/manage/user-notes.php
