Using Doctrine DBAL to count number of rows from SELECT query

Actually I thought I had looked really hard, but I just came across this Count Records Returned MySQL Doctrine

So the way to do it is via the rowCount() method.

Example:

$num_rows = $conn->executeQuery("SELECT * FROM users")->rowCount();

Another way to do this with Doctrine DBAL is to get the count as a field and return the column

    $sql = "SELECT count(*) AS Total FROM myTable WHERE myId = :myId";
    $stmt = $conn->prepare($sql);
    $stmt->bindValue('myId', $myId, PDO::PARAM_INT);
    $stmt->execute();
    $count = $stmt->fetchColumn(0);
