Review comment:
This can potentially cause NPE, @anuragaw can you check who are the users of
the method and potentially what must be the ideal return value? The
`createCountSelect` and its indirect users have atleast 70 usages
codebase-wide, therefore while fixing the bug, new regression should be avoided.
