To know the size of each database, the steps are as follows:
1. Enter the information_schema database (stored the information of other databases)
use information_schema;
2. Query the size of all data:
select concat(round(sum(data_length/1024/1024),2),'MB') as data from tables;
3. View the size of the specified database:
For example, view the size of the database home
select concat(round(sum(data_length/1024/1024),2),'MB') as data from tables where table_schema='home';
4. View the size of a table in the specified database
For example, view the size of the members table in the database home
select concat(round(sum(data_length/1024/1024),2),'MB') as data from tables where table_schema='home' and table_name='members';
