一.查看表空间大小

select dbf.tablespace_name,
       dbf.totalspace "总量(G)",
       dbf.totalblocks as 总块数,
       dfs.freespace "剩余总量(G)",
       dfs.freeblocks "剩余块数",
       (dfs.freespace / dbf.totalspace) * 100 "空闲比例"
  from (select t.tablespace_name,
               sum(t.bytes) / 1024 / 1024 / 1024 totalspace,
               sum(t.blocks) totalblocks
          from dba_data_files t
         group by t.tablespace_name) dbf,
       (select tt.tablespace_name,
               sum(tt.bytes) / 1024 / 1024 / 1024 freespace,
               sum(tt.blocks) freeblocks
          from dba_free_space tt
         group by tt.tablespace_name) dfs
 where trim(dbf.tablespace_name) = trim(dfs.tablespace_name);
--查看表空间是否自动增长

--创建临时表空间

create temporary tablespace temp_rqrq 
tempfile 'F:\oracle11g\oradata\orcl\temp_rqrq.dbf'
size 3024m 
autoextend on 
next 50m maxsize 5480m

--创建表空间

Oracle 创建表空间、用户、授权

--授权创建会话的权限

--授权连接，操作表权限
