1、查詢整個(gè)mysql數(shù)據(jù)庫,整個(gè)庫的大小;單位轉(zhuǎn)換為MB。
select concat(round(sum(DATA_LENGTH/1024/1024),2),'MB') as data from information_schema.TABLES
2、查詢mysql數(shù)據(jù)庫,某個(gè)庫的大小;
select concat(round(sum(DATA_LENGTH/1024/1024),2),'MB') as data from information_schema.TABLES where table_schema = 'testdb'
3、查看庫中某個(gè)表的大小;
select concat(round(sum(DATA_LENGTH/1024/1024),2),'MB') as data from information_schema.TABLES where table_schema = 'testdb' and table_name = 'test_a';
4、查看mysql庫中,test開頭的表,所有存儲(chǔ)大小;
select concat(round(sum(DATA_LENGTH/1024/1024),2),'MB') as data from information_schema.TABLES where table_schema = 'testdb' and table_name like 'test%';
