Mysql list tables and sizes - order by size

Question

What would be the query to list all tables in a database order by their size in mysql?

Answer 1

Try this...

SELECT TABLE_NAME, table_rows, data_length, index_length,  round(((data_length + index_length) / 1024 / 1024),2) "Size in MB" FROM information_schema.TABLES WHERE table_schema = "schema_name" ORDER BY (data_length + index_length) DESC; 

Note: Replace schema_name above with the name of your database

Answer 2

Run the following query in the mysql client

SELECT table_name AS "Tables",  round(((data_length + index_length) / 1024 / 1024), 2) "Size in MB"  FROM information_schema.TABLES  WHERE table_schema = "$DB_NAME" ORDER BY (data_length + index_length) DESC;
