J'ai quelques requêtes que vous pouvez exécuter par rapport à INFORMATION_SCHEMA

CAVEAT
Dans chaque requête, vous verrez (SELECT 3 pw)
. Le pw représente la puissance de 1024 pour afficher les résultats.
(SELECT 0 pw)
affichera le rapport en octets
(SELECT 1 pw)
affichera le rapport en kilo-octets
(SELECT 2 pw)
affichera le rapport en mégaoctets
(SELECT 3 pw)
affichera le rapport en GigaBytes
(SELECT 4 pw)
affichera le rapport en TeraBytes
(SELECT 5 pw)
affichera le rapport en PetaBytes (veuillez me contacter si vous exécutez celui-ci)
Voici une requête de rapport avec un peu moins de mise en forme:
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;
Essaie !!!
MISE À JOUR
Je viens d'exécuter la première requête telle quelle sur la base de données d'un client
mysql> SELECT IFNULL(B.engine,'Total') "Storage Engine",

-> SUBSTR(' KMGTP',pw+1,1),'B') "Index Size", CONCAT(LPAD(REPLACE(

Cela fonctionne tel quel.

, qui n'est pas une colonne dans information_schema.partitions. En dehors de cela, information_schema.partitions intercepte toutes les tables, même celles non partitionnées. N'oubliez pas d'exclureinformation_schema

de WHERE les clauses vérifiant table_schema.SELECT table_schema, sum(data_length) / 1024 / 1024 "data", sum(index_length) / 1024 / 1024 "index", sum( data_length + index_length ) / 1024 / 1024 "total" FROM information_schema.TABLES GROUP BY table_schema;
Est-ce que cela fonctionnera? Toute la requête information_schema / table_schema est nouvelle pour moi. (Si vous ne pouvez pas le dire, je suis assez nouveau dans tout cela :) Merci!
