给出具体update的语句
给出下面的查询:- REM tablespace report
- set linesize 200
- select a.tablespace_name,
- round(a.bytes_alloc / 1024 / 1024) megs_alloc,
- round(nvl(b.bytes_free, 0) / 1024 / 1024) megs_free,
- round((a.bytes_alloc - nvl(b.bytes_free, 0)) / 1024 / 1024) megs_used,
- round((nvl(b.bytes_free, 0) / a.bytes_alloc) * 100) Pct_Free,
- 100 - round((nvl(b.bytes_free, 0) / a.bytes_alloc) * 100) Pct_used,
- round(maxbytes / 1048576) Max
- from (select f.tablespace_name,
- sum(f.bytes) bytes_alloc,
- sum(decode(f.autoextensible, 'YES', f.maxbytes, 'NO', f.bytes)) maxbytes
- from dba_data_files f
- group by tablespace_name) a,
- (select f.tablespace_name, sum(f.bytes) bytes_free
- from dba_free_space f
- group by tablespace_name) b
- where a.tablespace_name = b.tablespace_name(+)
- union all
- select h.tablespace_name,
- round(sum(h.bytes_free + h.bytes_used) / 1048576) megs_alloc,
- round(sum((h.bytes_free + h.bytes_used) - nvl(p.bytes_used, 0)) /
- 1048576) megs_free,
- round(sum(nvl(p.bytes_used, 0)) / 1048576) megs_used,
- round((sum((h.bytes_free + h.bytes_used) - nvl(p.bytes_used, 0)) /
- sum(h.bytes_used + h.bytes_free)) * 100) Pct_Free,
- 100 -
- round((sum((h.bytes_free + h.bytes_used) - nvl(p.bytes_used, 0)) /
- sum(h.bytes_used + h.bytes_free)) * 100) pct_used,
- round(sum(f.maxbytes) / 1048576) max
- from sys.v_$TEMP_SPACE_HEADER h,
- sys.v_$Temp_extent_pool p,
- dba_temp_files f
- where p.file_id(+) = h.file_id
- and p.tablespace_name(+) = h.tablespace_name
- and f.file_id = h.file_id

- group by h.tablespace_name
- ORDER BY 1
- /
- select sum(SPACE),TS_NAME from dba_recyclebin group by ts_name;
