MySQL檢視資料庫表容量大小

select 

table_schema as
'資料庫',
sum(table_rows) as
'記錄數',
sum(truncate(data_length/1024/1024, 2)) as
'資料容量(mb)',
sum(truncate(index_length/1024/1024, 2)) as
'索引容量(mb)'
from information_schema.tables
group
by table_schema
order
bysum(data_length) desc, sum(index_length) desc;

select 

table_schema as
'資料庫',
table_name as
'表名',
table_rows as
'記錄數',
truncate(data_length/1024/1024, 2) as
'資料容量(mb)',
truncate(index_length/1024/1024, 2) as
'索引容量(mb)'
from information_schema.tables
order
by data_length desc, index_length desc;

select
