1. 查询表空间剩余字节大小SELECT TABLESPACE_NAME, SUM(BYTES)/1024/1024 AS "FREE SPACE(M)"
FROM DBA_FREE_SPACE
WHERE TABLESPACE_NAME = '&tablespace_name'
GROUP BY TABLESPACE_NAME;注：如果是临时表空间，请查询DBA_TEMP_FREE_SPACESELECT TABLESPACE_NAME, FREE_SPACE/1024/1024 AS "FREE SPACE(M)"
FROM DBA_TEMP_FREE_SPACE
WHERE TABLESPACE_NAME = '&tablespace_name';
