How to get the sizes of the tables of a mysql database

If you have a very big database with a lot of tables and you want to know which tables use more spaces, run the following query replacing %DB_NAME% with your database and %TABLE_NAME% if you know the table name.

    table_name AS `Table`, 
    round(((data_length + index_length) / 1024 / 1024), 2) `Size in MB` 
FROM information_schema.TABLES 
WHERE table_schema = "$DB_NAME"
    AND table_name = "$TABLE_NAME";
