title: Select distinct rows from a query
body: <p>I have the following SQL Server Query:</p>
  
  <pre><code>select flujo, FECHA from El_Bosque 
  where fecha between CONVERT(DATETIME,'2016-06-22 10:00:00',102) 
  and CONVERT(DATETIME,'2016-06-28 00:00:00',102) and ( flujo &gt;=0 ) 
  order by fecha asc
  </code></pre>
  
  <p>It returns:</p>
  
  <pre><code>0.84    2016-06-22 10:00:00.000
  0.84    2016-06-22 10:00:00.000
  0.83    2016-06-22 10:15:00.000
  0.83    2016-06-22 10:15:00.000
  0.81    2016-06-22 10:30:00.000
  0.81    2016-06-22 10:30:00.000
  </code></pre>
  
  <p>I would like to filter this query so I can only obtain distinct rows like this:</p>
  
  <pre><code>0.84    2016-06-22 10:00:00.000
  0.83    2016-06-22 10:15:00.000
  0.81    2016-06-22 10:30:00.000
  </code></pre>
  
  <p>Thank you in advance.</p>
