oracle表空间相关SQL语句

Oracle 数据库查看表空间的使用情况

SELECT d.tablespace_name,
space "SUM_SPACE(MB)",
space - NVL(free_space, 0) "USED_SPACE(MB)",
free_space "FREE_SPACE(MB)",
ROUND((1 - NVL(free_space, 0) / space) * 100, 2) "USED_RATE(%)",
ROUND(NVL(free_space, 0) * 100 / space, 2) "FREE_RATE(%)"
FROM (SELECT tablespace_name, ROUND(SUM(bytes) / (1024 * 1024), 2) space
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(+)
ORDER BY "USED_RATE(%)" DESC;
