title: Replace function combined with ltrim and rtrim
body: <p>Can someone please help me to understand the following code:</p>
  
  <pre><code>REPLACE(LTRIM(RTRIM(dbo.UFN_SEPARATES_COLUMNS(CompletionDetails, 3, ','))), '.', '') AS BuildRequestID,
  </code></pre>
  
  <p>Does it say remove all trailing and leading spaces, then replace 3 with comma. Next, if there is <code>.</code>, replace it with <code>' '</code>?</p>
