查看表空間使用情況(SQL)

mage border select 20px mono col gin 查詢 otto

   1: --查詢表空間使用情況
   2: SELECT Upper(F.TABLESPACE_NAME)         "表空間名",
   3:        D.TOT_GROOTTE_MB                 "表空間大小(M)",
   4:        D.TOT_GROOTTE_MB - F.TOTAL_BYTES "已使用空間(M)",

  11: FROM   (SELECT TABLESPACE_NAME,
  12:                Round(Sum(BYTES) / ( 1024 * 1024 ), 2) TOTAL_BYTES,
  13:                Round(Max(BYTES) / ( 1024 * 1024 ), 2) MAX_BYTES
  14:         FROM   SYS.DBA_FREE_SPACE
  15:         GROUP  BY TABLESPACE_NAME) F,
  16:        (SELECT DD.TABLESPACE_NAME,
  17:                Round(Sum(DD.BYTES) / ( 1024 * 1024 ), 2) TOT_GROOTTE_MB,
  18:                AUTOEXTENSIBLE,
  19:
--INCREMENT_BY的單位是數據塊的大小。數據塊大小一般為默認8k
  20:                Round(INCREMENT_BY * (select value/1024 from v$parameter where name=‘db_block_size‘)/1024, 2) INCREMENTSIZE
  21:         FROM   SYS.DBA_DATA_FILES DD
  22:         GROUP  BY DD.TABLESPACE_NAME,AUTOEXTENSIBLE,INCREMENT_BY) D
  23: WHERE  D.TABLESPACE_NAME = F.TABLESPACE_NAME
  24: ORDER  BY  "表空間名"

顯示結果如下:
