Hi everyone, im new here, so please correct me if i created or formated topic incorrectly. I found a problem. I have a simple query for my needs:

     $stmt = $dbh->prepare("SELECT concat(first_name,' ',last_name) as
     full_name,t.* FROM specialists t HAVING full_name like '%john%'");
     $stmt->execute();
     while($row = $stmt->fetch())
     {
        echo '<pre>'; var_dump($row); echo '</pre>';
     }

It works fine, until i add a param to my query:

     $stmt = $dbh->prepare("SELECT concat(first_name,' ',last_name) as
     full_name,t.* FROM specialists t HAVING full_name like '%:query%'");
     $stmt->execute();
     $query = 'londo';
     $stmt->bindParam(':query',$query);
     while($row = $stmt->fetch())
     {
        echo '<pre>'; var_dump($row); echo '</pre>';
     }

Now there is nothing in fetch(). Is it a bug ? Thanks. First - you prepare the query

Second - you create and 'bind' the parameters to it Third - you execute the now completed query Fourth - you process the results.
