[mysql] Узнаём размер БД через консоль

Вот собственно запрос:

SELECT table_schema "database_name", sum( data_length + index_length )/1024/1024 "Data Base Size in MB" FROM information_schema.TABLES GROUP BY table_schema;

Вывод будет в такой форме

+--------------------+----------------------+
| database_name      | Data Base Size in MB |
+--------------------+----------------------+
| information_schema |           0.00878906 |
| mysql              |           0.61256504 |
| performance_schema |           0.00000000 |
| stephensmedia      |           8.15625000 |
| tutology           |           3.56811810 |
