oracle创建新用户和用户表空间

1.首先,创建(新)用户:
create user username identified by password;
username:新用户名的用户名
password: 新用户的密码
也可以不创建新用户,而仍然用以前的用户,如:继续利用scott用户

2.创建表空间:
create tablespace tablespacename datafile 'd:\data.dbf' size xxxm;
tablespacename:表空间的名字
d:\data.dbf':表空间的存储位置
xxx表空间的大小,m单位为兆(M)
3.将空间分配给用户:
alter user username default tablespace tablespacename;
将名字为tablespacename的表空间分配给username

4.给用户授权:
grant create session,create table,unlimited tablespace to username;
grant create session,create table,unlimited tablespace to NAMEMATCHER;

5.然后再以楼主自己创建的用户登录,登录之后创建表即可。
conn username/password;

6.查看服务名
env |grep SID

7.授予dba权限
grant dba to username

7.使用上面的用户名、密码、sid登录plsql

 

每步执行的sql:(sjzx是数据库名、用户名、密码、表空间名)
(1)create user sjzx identified by sjzx
(2)create tablespace sjzx datafile 'D:\db\app\oradata\orcl\sjzx.dbf'
size 100m
autoextend on next 32m maxsize 2048m

(3)alter user sjzx default tablespace sjzx

(4)grant create session,create table,unlimited tablespace to sjzx

 

 

 

1.创建用户
create user user_name identified by "user_password"
default tablespace tbs_name
temporary tablespace temp profile DEFAULT;

2.授权
grant connect to user_name;
grant create indextype to user_name;
grant create job to user_name;
grant create materialized view to user_name;
grant create procedure to user_name;
grant create public synonym to user_name;
grant create sequence to user_name;
grant create session to user_name;
grant create table to user_name;
grant create trigger to user_name;
grant create type to user_name;
grant create view to user_name;
grant unlimited tablespace to user_name;
alter user user_name quota unlimited on tbs_name;

--查询用户默认使用的表空间
select username,default_tablespace from dba_users;
--修改默认表空间
alter user TRANSWATCH default tablespace TMS5_TABLES;
--给用户赋权限
grant create session,create table,unlimited tablespace to TRANSWATCH;
--查询用户使用的表空间
select table_name,tablespace_name from user_tables;
--查指定表空间下当前用户的所有表
select 'alter table '||table_name||' move tablespace TMS5_TABLES;' from

--查询索引
select * from user_indexes;

alter index SYS_IL0000077055C00004$$ rebuild tablespace TMS5_INDEXES;
alter index PK_SUPPORT_FILES rebuild tablespace TMS5_INDEXES;
...
--查询函LOB类型表所在索引表空间(ORA-02327: cannot create index on expression with datatype LOB 02327. 00000,报这个错是因为LOB类型导致)
select * from user_indexes where index_name like 'SYS%'
--表结构
desc SCREENING_IWL_ENTITY;
--移动含LOB类型表的索引到其他表空间
ALTER TABLE SCREENING_IWL_ENTITY MOVE LOB(DETAIL) STORE AS (TABLESPACE TMS5_INDEXES);
