body: <p>In red is using hash, I need to store hash key with multiple fields and values.
  I tried as below:</p>
  
  <pre><code>client.hmset("Table1", "Id", "9324324", "ReqNo", "23432", redis.print);
  client.hmset("Table1", "Id", "9324325", "ReqNo", "23432", redis.print);
  var arrrep = new Array();
  
  client.hgetall("Table1", function(err, rep){
   console.log(rep);
  });
  </code></pre>
  
  <p>Output is: <code>{ Id: '9324325', ReqNo: '23432' }</code></p>
