We may need to get the table sizes of the tables in a mysql database from the mysql command prompt.
SELECT TABLE_NAME AS `Table`, ROUND((DATA_LENGTH + INDEX_LENGTH) / 1024 ) AS `Size (KB)` FROM information_schema.TABLES WHERE TABLE_SCHEMA = "<database_name>" ORDER BY (DATA_LENGTH + INDEX_LENGTH) DESC;
Here <database_name> needs to be changed to your database name. Also you can get the sizes in MB or GB by adding /1024 required times. For example, to get the size in MB the code has to be changed as follows;
SELECT TABLE_NAME AS `Table`, ROUND((DATA_LENGTH + INDEX_LENGTH) / 1024/1024) AS `Size (MB)` FROM information_schema.TABLES WHERE TABLE_SCHEMA = "<database_name>" ORDER BY (DATA_LENGTH + INDEX_LENGTH) DESC
