本文介紹mysql檢視資料庫表容量大小的命令語句，提供完整查詢語句及例項，方便大家學習使用。
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
例：檢視mysql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 where table_schema='mysql' order by data_length desc, index_length desc;
