title: SSIS Expression Builder - How to find last occurrence of a character
body: <p>I have values that look like this:</p>
  
  <pre><code>D:\DM-250\Insert_Jobs-QA-UAT\14-FILE_A_UpdateInsert.dts
  
  D:\DM-250\Insert_Jobs-QA-UAT\Something_DaisyChain\14-stuff_and_things_UpdateInsert.dts
  
  D:\DM-250\14-another_file.dts
  </code></pre>
  
  <p>I want the very ends of these 3 values, starting from the last <code>"\"</code> character.</p>
  
  <p>I tried to use <code>FINDSTRING</code>, but I don't know how to grab the last occurrence of a character.</p>
  
  <p>Any suggestions?</p>
