If you have a lot of databases and you want to check their creation dates just run this SELECT.
If the ‘create_time’ is null then your user won’t have the necessary permissions.
SELECT table_schema, MAX(create_time) create_time FROM information_schema.tables -- where TABLE_SCHEMA ='myDb' -- uncomment for specific database GROUP BY TABLE_SCHEMA -- SORT BY create_time
Run the query in your favourite tool (like HeidiSQL)
