using bind concat in construct query
<p>I have the following query</p>

<pre><code>CONSTRUCT{
   ?entity a something;
    a label ?label .
} 
WHERE
{
   ?entity a something;
   a label ?label .
 BIND(CONCAT(STR( ?label ), " | SOME ADDITIONAL TEXT I WOULD LIKE TO APPEND MANUALLY") ) AS ?label ) .
}
</code></pre>

<p>I simply want to concatenate some text with <code>?label</code>, however when running the query I get the following error:</p>

<pre><code>BIND clause alias '?label' was previously used
</code></pre>

<p>I only want to return a single instance of <code>?label</code> hence, I defined it in the construct clause.</p>
