SQL to check if database is empty (no tables)

Question

I need to check if a database is totally empty (no tables) using an SQL query. How can this be done?

Thanks for the help!

Answer 1

To get a list of all databases without tables in MySQL:

use information_schema

select schema_name from `schemata` s
  left join `tables` t on s.schema_name = t.table_schema
  where t.table_name is null
;
