title: How can I display chinese contents from database?
body: <p>I have created a connection with </p>
  
  <pre><code>library(RODBC)
  con &lt;- odbcConnect("DV1", uid = "aaa", pwd = "bbb")
  </code></pre>
  
  <p>And implement the SQL command:</p>
  
  <pre><code>line.gps &lt;- sqlQuery(con, "SELECT LINE_NAME FROM NJGJ_BUS_TRIP_EX WHERE LINE_NAME IN('2路')")
  </code></pre>
  
  <p>But there is no result:</p>
  
  <pre><code>[1] LINE_NAME
  &lt;0 行&gt; (或0-长度的row.names)
  </code></pre>
  
  <p>Actually there is data when I implement this sql command in database studio.</p>
  
  <p>Is there any way to impliment it?</p>
