If you want to query in the INFORMATION_SCHEMA database I have the following:

Table of Contents Show

How big can MySQL database be?
What is the largest Oracle database in the world?
Which database is best for MySQL?

Total Storage By Database in MB

SELECT DBName,CONCAT(LPAD(FORMAT(SDSize/POWER(1024,pw),3),17,' '),' ',

GROUP BY DB WITH ROLLUP) AA,(SELECT 2 pw) BB ORDER BY (SDSize+SXSize);

Total Storage By Storage Engine

SELECT IFNULL(B.engine,'Total') "Storage Engine",

WHERE table_schema NOT IN ('mysql','information_schema','performance_schema')
AND engine IS NOT NULL GROUP BY engine WITH ROLLUP) B,(SELECT 2 pw) A ORDER BY TSize;

Total Storage Database and Storage Engine

SELECT IF(ISNULL(B.table_schema)+ISNULL(B.engine)=2,
"Storage for All Databases",IF(ISNULL(B.table_schema)+ISNULL(B.engine)=1,
CONCAT("Storage for ",B.table_schema),

FROM information_schema.tables WHERE table_schema NOT IN
('mysql','information_schema','performance_schema') AND
engine IS NOT NULL GROUP BY table_schema,engine WITH ROLLUP) B,
(SELECT 2 pw) A ORDER BY TSize;

Please note in all the queries you see a subquery that looks like this: (SELECT 2 pw)

(SELECT 0 pw) present the Database Sizes in Bytes
(SELECT 1 pw) present the Database Sizes in KiloBytes
(SELECT 2 pw) present the Database Sizes in MegaBytes
(SELECT 3 pw) present the Database Sizes in GigaBytes
(SELECT 4 pw) present the Database Sizes in TeraBytes
(SELECT 5 pw) present the Database Sizes in PetaBytes (If you ever run with this, email me)
