db-size.sql

# Adapted from http://stackoverflow.com/questions/1733507/how-to-get-size-of-mysql-database

SELECT Round(Sum(data_length + index_length) / 1024 / 1024, 1) "DB Size in MB" 
FROM   information_schema.tables 
WHERE table_schema = "database_name" # Replace this with the name of the database you want to inspect
GROUP BY table_schema;
