Answer 1

You can select count(*) from information_schema.tables if you have priviliges on it.

select count(*) from information_schema.tables
where table_schema = <My Schema>
and table_type = 'BASE TABLE';

and filter on table_rows column for empty yables:

 select count(*) from information_schema.tables
 where table_schema = <My Schema>
 and table_type = 'BASE TABLE'
 and table_rows = 0;
