Hi Prasanna,
Thanks for your reply. I tried to use it in the following way. But after adding the statement, javascript stopped working.
sforce.connection.sessionId = “{!$Api.Session_ID}";
alert('Select Name, Id From Contact ORDER BY Name');
var qr = sforce.connection.query("Select Name,Id From Contact ORDER BY Name") ;
alert('qr '+qr);
