title: OR (||) statement in mysql query
body: <p>i have different tables which have rows for IDs. but rows in all table have different names like a_id, m_d etc. 
  so i am just curious to know if there is any working "OR statement" that i can use in mysql query?</p>
  
  <pre><code>&lt;?php  
      include('db.php');
      include('Admin.php');
      $table=$_GET['tbl'];
      $id=      $_GET['id'];
  
      $query="DELETE FROM `$table` WHERE (m_id=$id  OR id=$id)";
       mysqli_query($conn,$query);
  
  ?&gt; 
  </code></pre>
