title: Error invalid object name when connectin with node-mssql
body: <p>I am using the following code to connect to Ms SQL-Server</p>
  
  <pre><code>var node_mssql = require('node-mssql');
  
  /* add configuration to query object */
  var queryObj = new node_mssql.Query({
      host: '127.0.0.1',     // You can use 'x.x.x.x\\instance' to connect to named instance 
      port: 1433,
      username: 'myuser',
      password: 'mypwd',
      database: 'persondb'
  });
  
  /* set table name to operate */
  queryObj.table('dbo.Person');
  
  /* set update query condition */
  queryObj.where({
      'FirstName': 'Mathias',
  })
  
  /* run update query and fetch response */
  queryObj.select(function(results) {
      //  success callback 
      console.log(results);
  }, function(err, sql) {
      //  failed callback 
      if(err)
          console.log(err);
  
      console.log(sql);
  });
  </code></pre>
  
  <p>I get the error</p>
  
  <pre><code>Invalid object name "undefined.dbo.Person."
  
  Select  * FROM undefined.dbo.Person WHERE FirstName = 'Mathias'
  </code></pre>
  
  <p>It looks like the servername is not picked up. How can I fix this to connect to the Sql-Server?</p>
