title: Where statement with decimal
body: <p>I'm creating a little project to manage money.   </p>
  
  <p>I have an option to filter the content in the <code>DataGrid</code> (the values are the ones that are in the database), one of the filtering options is to filter by amount of money but I have a problem. How I search using <code>decimal</code> values in <code>SQL</code>?</p>
  
  <p>One <code>SQL query</code> that I use is: </p>
  
  <pre><code>Select qtd As 'Monetary amount' 
  From mm_registos 
  Where qtd &gt; 10
  </code></pre>
  
  <p>But I want to filter using <code>decimal</code> values like:</p>
  
  <pre><code>Select qtd As 'Monetary amount' 
  From mm_registos 
  Where qtd &gt; 10,8
  </code></pre>
  
  <p>Can anyone tell me the correct <code>query</code>?</p>
