1.查看所有數據庫容量大小
select table_schema as '數據庫', sum(table_rows) as '記錄數', sum(truncate(data_length/1024/1024, 2)) as '數據容量(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.查看所有數據庫各表容量大小
select table_schema as '數據庫', table_name as '表名', table_rows as '記錄數', truncate(data_length/1024/1024, 2) as '數據容量(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.查看指定數據庫容量大小
例:查看mysql庫容量大小
select table_schema as '數據庫', sum(table_rows) as '記錄數', sum(truncate(data_length/1024/1024, 2)) as '數據容量(MB)', sum(truncate(index_length/1024/1024, 2)) as '索引容量(MB)' from information_schema.tables where table_schema='mysql';
4.查看指定數據庫各表容量大小
例:查看mysql庫各表容量大小
select table_schema as '數據庫', table_name as '表名', table_rows as '記錄數', truncate(data_length/1024/1024, 2) as '數據容量(MB)', 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;
