Delete query in Alasql

i am new to Alasql.

In my nodejs code i have written below piece of code for delete an item. but it is not getting deleted. Any help?

sqldb.exec('DELETE FROM Cores WHERE [node-id] ='%s'', Id);
sqldb.exec('DELETE FROM Cores WHERE [node-id] = ?', Id);
sqldb.exec('DELETE FROM Cores WHERE [node-id] ='+ Id);

i tried all the above combinations it is not working
