Hi,
You have to write dynamic query within Start method and then do the return via
Database.QueryLocator(DynamicQuery);
For reference please go through this

Hi Bhaskar/Souvik,
As you can see in the link provided by Souvik,
The start method collects the records or objects to be passed to the interface method execute.
It returns either a Database.QueryLocator object or an iterable that contains the records or objects being passed into the job.
In your case, you will have to use Custom Iterators
