title: sqlFetch Table not found error
body: <p>After I use </p>
  
  <pre><code>cn&lt;-odbcConnect(...)
  </code></pre>
  
  <p>to connect to MS SQL Server. I can successfully get data using: </p>
  
  <pre><code>tmp &lt;- sqlQuery(cn, "select * from MyTable")
  </code></pre>
  
  <p>But if I use</p>
  
  <pre><code>tmp &lt;- sqlFetch(cn,"MyTable") 
  </code></pre>
  
  <p>R would complain about "Error in odbcTableExists(channel, sqtable) : table not found on channel". Did I miss anything here?</p>
