Имам няколко страхотни големи запитвания за споделяне:

ПРЕДУПРЕЖДЕНИЕ
Във всяка заявка ще видите (SELECT 3 pw)
. Pw означава силата на 1024 за показване на резултатите.
(SELECT 0 pw)
ще покаже отчета в байтове(SELECT 1 pw)
ще покаже отчета в килобайтове(SELECT 2 pw)
ще покаже отчета в мегабайтове(SELECT 3 pw)
ще покаже отчета в гигабайтове(SELECT 4 pw)
ще покаже отчета в терабайти(SELECT 5 pw)
ще покаже отчета в PetaBytes (моля, свържете се с мен, ако стартирате този)
Ето заявка за отчет с малко по-малко форматиране:
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;
Повярвайте ми, направих тези заявки преди повече от 4 години и все още ги използвам днес.
АКТУАЛИЗИРАНЕ 2013-06-24 15:53 EDT
имам нещо ново. Промених заявките, така че да не се налага да задавате pw
параметър за различни дисплейни единици. Всеки дисплей на единица се изчислява за вас.
