sforce.connection.query is not working on visualforce tabs

Question

I have written one visualforce page and added custom visualforce tab for that page. Now I have opened that tab in Console application. It is not working.

Could you please help me on this.

`

<apex:page >
<script src="/soap/ajax/33.0/connection.js" type="text/javascript"></script>
<script src="/soap/ajax/33.0/apex.js" type="text/javascript"></script>
<script type="text/javascript">
    function fun()
    {
            alert('Hi');
            var qr = sforce.connection.query("Select Id, MasterLabel From venkatproject__Test2__mdt");
            alert('I am here');
            var records = qr.getArray("records");
            alert(records[0].MasterLabel);
            alert(records.length);
    }              
</script>
<apex:form >
<apex:pageBlock >
<apex:pageBlockButtons location="bottom">
<apex:commandLink styleClass="btn" style="text-decoration:none;padding:4px;" value="New Case" id="clink" onclick="fun(); return false;"/>
</apex:pageBlockButtons>
</apex:pageBlock>
</apex:form>
</apex:page>

It will work, but need to some small addition : -

after <apex:page> just add below line : -

 <script type="text/javascript">
        var __sfdcSessionId = '{!GETSESSIONID()}';
 </script>

i have run your code in Console application and it is showing all the alert. Please find the attached screenshot
