标签：网上 tables ble sum sele user 表名 byte rac
要求计算某个表所占表空间的大小，网上查了些资料用到了oracle的3个视图。具体sql如下
select segment_name as tablename, round(bytes / (select sum(a.bytes) from dba_data_files a, user_users b where a.tablespace_name = b.default_tablespace) * 100,3) from user_segments where segment_name = ‘表名‘
该sql只保留了小数点后3位
