How do I determine the size of a specific MySQL database?

Determining MySQL Database Size

If you need to ascertain the size of a specific MySQL database, such as "v3," here's how you can proceed:

Database Size Query

To retrieve the size of the database, execute the following query:

SELECT table_schema "DB Name",
        ROUND(SUM(data_length + index_length) / 1024 / 1024, 1) "DB Size in MB" 
FROM information_schema.tables 
GROUP BY table_schema; 

This query was sourced from the MySQL forums and provides detailed instructions for its execution.

Explanation

The above query:

• Retrieves the database name ("DB Name")
• Calculates and displays the database size in megabytes ("DB Size in MB")
• Does not reference specific database name, allowing you to apply it to any database, including "v3"
