title: Specific text to ROLLUP / Subtotals in Oracle
body: <p>I have following Query:</p>
  
  <pre><code>  SELECT REL_NR, ERR_CODE, COUNT (ERR_CODE)
    FROM ZDL_ERR
    WHERE ERR_CODE &gt; 0
    GROUP BY ROLLUP (REL_NR, ERR_CODE)
    ORDER BY REL_NR DESC, ERR_CODE;
  </code></pre>
  
  <p>with following Output:</p>
  
  <pre><code>196 1148   16
  196 1180 2288
  196 1181  177
  196      2481
  </code></pre>
  
  <p>Is there a way to give a ROLLUP a text so it displays something like this:</p>
  
  <pre><code>196 1148   16
  196 1180 2288
  196 1181  177
  Subtotal 2481
  </code></pre>
