查看表空间
抄来的，记一下：SELECT c.tablespace_name "表空间", ROUND(a.bytes / 1048576, 2) "表空间大小", ROUND((a.bytes - b.bytes) / 1048576, 2) "已使用空间", ROUND(b.bytes / 1048576, 2) "剩余空间", ROUND(b.bytes / a.bytes * 100, 2) || '%' "剩余百分比"FROM (SELECT tablespace_name, SUM(a.bytes) bytes FROM sys.DBA_DATA_FILES a GROUP BY tablespace_name) a, (SELECT a.tablespace_name, NVL(SUM(b.bytes), 0) bytes FROM sys.DBA_DATA_FILES a, sys.DBA_FREE_SPACE b WHERE a.tablespace_name = b.tablespace_name(+) AND a.file_id = b.file_id(+) GROUP BY a.tablespace_name) b, sys.DBA_TABLESPACES c WHERE a.tablespace_name = b.tablespace_name(+) AND a.tablespace_name = c.tablespace_name ORDER BY ROUND(b.bytes / 1048576, 2);
