title: Multiple UPDATE, same column, different values, different WHERE conditions
body: <p>I am trying to update a field with different conditions in where.
  Actually I have the next instructions: </p>
  
  <pre><code>Update StmHistItm Set SHI_nPayable = @minPayable where SHI_iItemPK = @minrecno
  Update StmHistItm Set SHI_nPayable = @maxPayable where SHI_iItemPK = @maxrecno
  </code></pre>
  
  <p>Is there a way to do this two instruction in just one?</p>
