CAVEAT
Di masing-masing dari tiga (3) pertanyaan, Anda akan melihat (SELECT 3 pw)
. The pw
singkatan Power Of 1024 untuk menampilkan hasil dalam satuan tertentu:
(SELECT 0 pw)
akan Menampilkan Laporan dalam Bytes
(SELECT 1 pw)
akan Menampilkan Laporan dalam KiloBytes
(SELECT 2 pw)
akan Menampilkan Laporan dalam MegaBytes
(SELECT 3 pw)
akan Menampilkan Laporan di GigaBytes
(SELECT 4 pw)
akan Menampilkan Laporan dalam TeraBytes
(SELECT 5 pw)
akan Menampilkan Laporan di PetaBytes (silakan hubungi saya jika Anda menjalankan ini)
Berikut adalah kueri laporan dengan sedikit pemformatan di 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;
