Please read the documentation first.
It seems you are trying to get the states, inside the View, with a query.
You need to separate the view from the model.
Create a State model.
Use something like this in your controller:
$this->loadModel('State');
$states = $this->State->find('list'); // this will create a key => value array with the IDs and names
$this->set('states', $states);
In your view, use
<table width="380">
<tr>
<?php foreach ($states as $stateId => $stateName) {
<td class="table_txt"><a class="thickbox tn" href="demo.php?state_name=<?php echo $stateName?>&state_id=<?php echo $stateId?>&height=430&height=430&width=700&inlineId=myOnPageContent"><?php echo $stateName ?>></a></td>
<?php } ?>
</tr>
You might still need some changes, but this is the main idea.
