1.檢視所有資料庫容量大小

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 by sum(data_length) desc, sum(index_length) desc;

2.檢視所有資料庫各表容量大小

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;

3.檢視指定資料庫容量大小

例:檢視mysql庫容量大小

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

where table_schema='mysql';

4.檢視指定資料庫各表容量大小

truncate(index_length/1024/1024, 2) as '索引容量(mb)'

from information_schema.tables

where table_schema='mysql'

order by data_length desc, index_length desc;
