MySQL Workbench Database Sizes I'm trying to find the total size on the hard disk that all of my MySQL Workbench databases are using.

Does anyone know of an easy way to figure this out?

If nothing else, the default location mysql/workbench uses for saving the raw data on a windows machine?

Thanks in advance!

I have some queries you can run against the INFORMATION_SCHEMA

Run this to get the Total MySQL Data and Index Usage By Storage Engine

SELECT IFNULL(B.engine,'Total') "Storage Engine",
CONCAT(LPAD(REPLACE(FORMAT(B.DSize/POWER(1024,pw),3),',',''),17,' '),' ',
SUBSTR(' KMGTP',pw+1,1),'B') "Data Size", CONCAT(LPAD(REPLACE(
FORMAT(B.ISize/POWER(1024,pw),3),',',''),17,' '),' ',
SUBSTR(' KMGTP',pw+1,1),'B') "Index Size", CONCAT(LPAD(REPLACE(
FORMAT(B.TSize/POWER(1024,pw),3),',',''),17,' '),' ',
SUBSTR(' KMGTP',pw+1,1),'B') "Table Size" FROM
(SELECT engine,SUM(data_length) DSize,SUM(index_length) ISize,
SUM(data_length+index_length) TSize FROM
information_schema.tables WHERE table_schema NOT IN
('mysql','information_schema','performance_schema') AND
engine IS NOT NULL GROUP BY engine WITH ROLLUP) B,
(SELECT 3 pw) A ORDER BY TSize;

CAVEAT

In each query, you will see (SELECT 3 pw). The pw stands for the Power Of 1024 to display the results.


(SELECT 0 pw) will Display the Report in Bytes
(SELECT 1 pw) will Display the Report in KiloBytes
(SELECT 2 pw) will Display the Report in MegaBytes
(SELECT 3 pw) will Display the Report in GigaBytes
(SELECT 4 pw) will Display the Report in TeraBytes
(SELECT 5 pw) will Display the Report in PetaBytes (please contact me if you run this one)


Here is a report query with a little less formatting:

SELECT IFNULL(db,'Total') "Database",
datsum / power(1024,pw) "Data Size",
ndxsum / power(1024,pw) "Index Size",
totsum / power(1024,pw) "Total"
FROM (SELECT db,SUM(dat) datsum,SUM(ndx) ndxsum,SUM(dat+ndx) totsum
FROM (SELECT table_schema db,data_length dat,index_length ndx
FROM information_schema.tables WHERE engine IS NOT NULL
AND table_schema NOT IN ('information_schema','mysql')) AA
GROUP BY db WITH ROLLUP) A,(SELECT 1 pw) B;


Give it a Try !!!

UPDATE 

I just ran the first query as is on a client's DB

mysql&gt; SELECT IFNULL(B.engine,'Total') "Storage Engine",
    -&gt; CONCAT(LPAD(REPLACE(FORMAT(B.DSize/POWER(1024,pw),3),',',''),17,' '),' ',
    -&gt; SUBSTR(' KMGTP',pw+1,1),'B') "Data Size", CONCAT(LPAD(REPLACE(
    -&gt; FORMAT(B.ISize/POWER(1024,pw),3),',',''),17,' '),' ',
    -&gt; SUBSTR(' KMGTP',pw+1,1),'B') "Index Size", CONCAT(LPAD(REPLACE(
    -&gt; FORMAT(B.TSize/POWER(1024,pw),3),',',''),17,' '),' ',
    -&gt; SUBSTR(' KMGTP',pw+1,1),'B') "Table Size" FROM
    -&gt; (SELECT engine,SUM(data_length) DSize,SUM(index_length) ISize,
    -&gt; SUM(data_length+index_length) TSize FROM
    -&gt; information_schema.tables WHERE table_schema NOT IN
    -&gt; ('mysql','information_schema','performance_schema') AND
    -&gt; engine IS NOT NULL GROUP BY engine WITH ROLLUP) B,
    -&gt; (SELECT 3 pw) A ORDER BY TSize;

It works as is.
