PDO提取不返回表中的任何行

Question

为什么我的PDO提取没有从表中返回任何行？

    $sql = "SELECT * from ts_rounds WHERE current=:current";
    $stm = $pdo->prepare( $sql );
    $stm->execute( array( ':current' => 1 ) );
    $rows = $stm->fetch();
    echo $row["name"];

Answer 1

把第一行中的=后面：

$sql = "SELECT * from ts_rounds WHERE current=:current";
