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.tablesorder 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.tableswhere 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.tableswhere table_schema='mysql'order by data_length desc, index_length desc;
