database-comparison

I have 2 identical databases. abc15 and abc18. But one of the database has one extra table and I need to find that. I thought the following query should return it, but is it not showing the record that I expect.

select * from information_schema.tables as a
    left join information_schema.tables as b
        on a.TABLE_SCHEMA=b.TABLE_SCHEMA AND a.TABLE_NAME=b.TABLE_NAME
    where a.TABLE_SCHEMA = 'abc15' AND b.TABLE_SCHEMA='abc18' and
        b.TABLE_NAME IS NULL
