title: Simple doctrine query -> one specific row and column
body: <p>I do have a table called <code>"tax"</code> with two column <code>"id | tax_value"</code>. I can list the table with an <code>foreach</code> very well.</p>
  
  <p>Now my question, how does the code look like when I just want to have 
  one specfic row and column in the php code? I don't want it in the query!!!</p>
  
  <p>for example:</p>
  
  <pre><code>column 2 (tax_value)
  
  row 1.
  </code></pre>
  
  <p>The query gives me an array, right?</p>
