Hızlı bir şekilde belirli bir MySQL tablo alarak belirlemek. Tablo hali hazırda ya da Orada olabilir.

Bir tablo için mydb.mytable için bu çalıştırın:

BAYT

SELECT (data_length index_length) tablesize
FROM information_schema.tables
WHERE table_schema='mydb' and table_name='mytable';

KİLOBAYT

SELECT (data_length index_length)/power(1024,1) tablesize_kb
FROM information_schema.tables
WHERE table_schema='mydb' and table_name='mytable';

MEGABAYT

SELECT (data_length index_length)/power(1024,2) tablesize_mb
FROM information_schema.tables
WHERE table_schema='mydb' and table_name='mytable';

GİGABAYT

SELECT (data_length index_length)/power(1024,3) tablesize_gb
FROM information_schema.tables
WHERE table_schema='mydb' and table_name='mytable';
