方法一：
SELECT D.TABLESPACE_NAME,
SPACE || 'M' "SUM_SPACE(M)",
BLOCKS "SUM_BLOCKS",
SPACE - NVL (FREE_SPACE, 0) || 'M' "USED_SPACE(M)",
ROUND ( (1 - NVL (FREE_SPACE, 0) / SPACE) * 100, 2) || '%'
"USED_RATE(%)",
FREE_SPACE || 'M' "FREE_SPACE(M)"
FROM ( SELECT TABLESPACE_NAME,
ROUND (SUM (BYTES) / (1024 * 1024), 2) SPACE,
SUM (BLOCKS) BLOCKS
FROM DBA_DATA_FILES
GROUP BY TABLESPACE_NAME) D,
( SELECT TABLESPACE_NAME,
ROUND (SUM (BYTES) / (1024 * 1024), 2) FREE_SPACE
FROM DBA_FREE_SPACE
GROUP BY TABLESPACE_NAME) F
WHERE D.TABLESPACE_NAME = F.TABLESPACE_NAME(+)
UNION ALL
SELECT D.TABLESPACE_NAME,
SPACE || 'M' "SUM_SPACE(M)",
BLOCKS SUM_BLOCKS,
USED_SPACE || 'M' "USED_SPACE(M)",
ROUND (NVL (USED_SPACE, 0) / SPACE * 100, 2) || '%' "USED_RATE(%)",
NVL (FREE_SPACE, 0) || 'M' "FREE_SPACE(M)"
FROM ( SELECT TABLESPACE_NAME,
ROUND (SUM (BYTES) / (1024 * 1024), 2) SPACE,
SUM (BLOCKS) BLOCKS
FROM DBA_TEMP_FILES
GROUP BY TABLESPACE_NAME) D,
( SELECT TABLESPACE_NAME,
ROUND (SUM (BYTES_USED) / (1024 * 1024), 2) USED_SPACE,
ROUND (SUM (BYTES_FREE) / (1024 * 1024), 2) FREE_SPACE
FROM V$TEMP_SPACE_HEADER
GROUP BY TABLESPACE_NAME) F
WHERE D.TABLESPACE_NAME = F.TABLESPACE_NAME(+)
ORDER BY 1;

查询结果格式如下：





方法2：

SELECT UPPER(F.TABLESPACE_NAME),D.TOT_GROOTTE_MB,D.TOT_GROOTTE_MB,F.TOTAL_BYTES,TO_CHAR(ROUND((D.TOT_GROOTTE_MB - F.TOTAL_BYTES) / D.TOT_GROOTTE_MB * 100, 2),'990.99'), F.TOTAL_BYTES, F.MAX_BYTES FROM (SELECT TABLESPACE_NAME,ROUND(SUM(BYTES) / (1024 * 1024), 2) TOTAL_BYTES,ROUND(MAX(BYTES) / (1024 * 1024), 2) MAX_BYTES FROM SYS.DBA_FREE_SPACE GROUP BY TABLESPACE_NAME) F,(SELECT DD.TABLESPACE_NAME,ROUND(SUM(DD.BYTES) / (1024 * 1024), 2) TOT_GROOTTE_MB FROM SYS.DBA_DATA_FILES DD GROUP BY DD.TABLESPACE_NAME) D WHERE D.TABLESPACE_NAME = F.TABLESPACE_NAME ORDER BY 4 DESC;


查询结果格式如下：
