VORBEHALT
In jeder der drei (3) Abfragen sehen Sie (SELECT 3 pw)
. Das pw
steht für die Power Of 1024, um die Ergebnisse in bestimmten Einheiten anzuzeigen:
(SELECT 0 pw)
zeigt den Bericht in Bytes an
(SELECT 1 pw)
zeigt den Bericht in Kilobyte an
(SELECT 2 pw)
zeigt den Bericht in MegaBytes an
(SELECT 3 pw)
zeigt den Bericht in GigaBytes an
(SELECT 4 pw)
zeigt den Bericht in TeraBytes an
(SELECT 5 pw)
zeigt den Bericht in PetaBytes an (bitte kontaktieren Sie mich, wenn Sie diesen ausführen)
Hier ist eine Berichtsabfrage mit etwas weniger Formatierung in KB
:
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;
