title: Sequelize set limit to max row count
body: <p>From front end I'm sending 2 type of param to <em>Sequelize</em></p>
  
  <p><strong>1st Param :</strong> <code>{}</code></p>
  
  <p><strong>2nd Param:</strong> <code>{page: '1', start: '0', limit: '30' }</code></p>
  
  <p><strong>My Sequelize query:</strong></p>
  
  <pre><code>myTable.findAndCountAll({
      .....
      offset: (req.query.start) ? parseInt(req.query.start) : 0,
      limit: (req.query.limit) ? parseInt(req.query.limit) : 30
  .........
  </code></pre>
  
  <p>For 1st param by default it's setting <strong>limit to 30</strong></p>
  
  <p>And for the 2nd param it's setting <strong>limit</strong> as the param sending.</p>
  
  <p>My problem here is, I need to set the default limit for the 1st param to return all row.</p>
  
  <p>Tried to set <code>null</code> for default like <code>limit: (req.query.limit) ? parseInt(req.query.limit) : null</code> which setting default limit to <strong>10000000000000</strong>, what I don't want.</p>
  
  <p>If there any specific way to do this might help.</p>
