Review Comment:
Thx for your reply.
The abstract method `toSqlImpl()` will be overrided in each subclass. So
there is no need to throw out exceptions.
The only situation is that a newly added subclass, which its sql digest
needs to be different from sql impl, should override this method.
Added comments over this method to remind developers.
