===

I am developing app in android phonegap using javascript.I have tried the insert query in sqlite with Not Exists.

Here is my code:

    var name='aaaaa';
    tx.executeSql('INSERT INTO Demo(Id,Name) SELECT ('1','+name+') WHERE NOT EXISTS (SELECT 1 FROM Demo WHERE Id='1')');

When i give one column name its working fine.But when i give two or more columns (For eg:Id,Name,Address)its not working.Please kindly guide me.Thanks in Advance.
