创建oracle用户，给用户授权

1、查询所有表空间

select dbf.tablespace_name,

dbf.totalspace "总量(M)",

dbf.totalblocks as 总块数,

dfs.freespace "剩余总量(M)",

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 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 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);

2、查询表空间HBZF的信息（如无可用的表空间需要新建一个表空间）

select t.*  from sys.dba_data_files t where t.tablespace_name ='HBZF';

3、创建新的用户

create user bthb_wjgl

  identified by "bthb_wjgl"

  default tablespace HBZF 

  profile DEFAULT

  ACCOUNT UNLOCK;

4、给用户授权

grant connect,dba to bthb_wjgl;

5、查询HBZF表空间的所有用户

select * from dba_users t where t.default_tablespace ='HBZF'
