title: Update Top in Visual FoxPro
body: <p>I'm accessing a Visual FoxPro Table (DBF File) via VFP OleDB Provider in a C# Application.
  Is there an equivalent of <code>UPDATE TOP</code> (MS SQL) in VFP?</p>
  
  <p>This is my current Query:</p>
  
  <pre><code>UPDATE HM_LIST
  SET 
    HM_DATE=DATE(2014,5,22) , 
    HM_STATION="CM_PC" , 
    HM_TIME="17:06" , 
    HM_USER="TEST" 
  WHERE 
    HM_STATION='' 
    AND HM_TIME='' 
    AND HM_USER=''
  </code></pre>
  
  <p>The problem is, all rows are matching to my parameters.
  But I want to update only one of those matching rows.</p>
  
  <p>There is no Primary_Key.
  I can't use <code>INSERT</code>.</p>
  
  <p><strong>Table</strong></p>
