title: Remove MailMerge data source via OpenXML
body: <p>I have some code that uses Open XML to open up a .docx file, find all MailMerge fields, and replace them with data (ignoring the datasource that may have been provided).</p>
  
  <p>I initially tested this against a document created in Office 2007 and it seemed to work great. </p>
  
  <p>We then created one in 2003 based off an Excel spreadsheet data source and saved it to 2007 .docx format. When we open the file produced by my code, Word warns the user that it is going to execute some SQL, specifically <code>SELECT * from 'Sheet1$'</code>. It has options of Yes/No. Selecting <em>Yes</em> requires I find the data source. Selecting <em>No</em> brings me to the document, which appears to be correct.</p>
  
  <p>I'm not sure why I'm now seeing this pop-up. Perhaps it's due to a different data source for the 2003 document? </p>
  
  <p>My hope was that there was a way to delete all references to any datasources and that the pop-up wouldn't show. I found <a href="http://social.msdn.microsoft.com/Forums/en-US/oxmlsdk/thread/8b363660-cc7f-4b7d-addf-30df57a0ecd6" rel="nofollow noreferrer">this</a>, but it doesn't seem to work. Any suggestions?</p>
