1、查询表空间的总容量
select a.TABLESPACE_NAME, sum(a.BYTES) / 1024 / 1024 as MB from sys.dba_data_files a group by a.TABLESPACE_NAME
2、查询表空间的空闲容量
select b.TABLESPACE_NAME, count(1) as extends, sum(b.BYTES) / 1024 / 1024 as MB, sum(b.BLOCKS) as blocks from sys.dba_free_space b group by b.TABLESPACE_NAME
3、查询表空间的使用情况
select total.TABLESPACE_NAME, round(total.MB, 2) as TOTAL_MB, round(total.MB - free.MB, 2) as USED_MB, ROUND((1 - free.MB / total.MB) * 100, 2) || ‘%‘ as USED_PCT, ROUND(free.MB, 2) as FREE_mb from (select a.TABLESPACE_NAME, sum(a.BYTES) / 1024 / 1024 as MB from sys.dba_data_files a group by a.TABLESPACE_NAME) total, (select b.TABLESPACE_NAME, count(1) as extends, sum(b.BYTES) / 1024 / 1024 as MB, sum(b.BLOCKS) as blocks from sys.dba_free_space b group by b.TABLESPACE_NAME) free where total.TABLESPACE_NAME = free.TABLESPACE_NAME
