How to Determine the Size of a MySQL Database?

Determining the Size of a MySQL Database

The size of a MySQL database can be crucial information for managing storage allocation and optimizing performance. To determine the database size, the following query can be executed:

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 returns the size of all databases, including the "v3" database mentioned in the question. The calculated value is rounded to one decimal point and displayed in megabytes. Running this query will provide the necessary information to determine the size of the "v3" database.

The query was sourced from the MySQL forums, where additional guidance and troubleshooting information can be found.
