Check table size in mb

README.md

In this example using the bookstore database, 
we’re combining the DATA_LENGTH and INDEX_LENGTH as bytes, 
then dividing it by 1024 twice to convert into kilobytes and then megabytes.

check-specific.sql

SELECT
  TABLE_NAME AS `Table`,
  ROUND((DATA_LENGTH + INDEX_LENGTH) / 1024 / 1024) AS `Size (MB)`
FROM
  information_schema.TABLES
WHERE
  TABLE_SCHEMA = "bookstore"
ORDER BY
  (DATA_LENGTH + INDEX_LENGTH)
DESC;
