title: MySQL function to quote identifiers with backticks
body: <p>Is there a MySQL built-in function that surrounds indentifiers (simple or qualified) with backticks? I.e. such function <code>f</code> would work like:</p>
  
  <p><code>f('my')</code> would return <code>`my`</code>,</p>
  
  <p><code>f('my.table')</code> would return <code>`my`.`table`</code>, and</p>
  
  <p><code>f(`my`)</code> would return <code>`my`</code></p>
