1、查看數據庫中有哪些用戶? select username from all_users;
2、查看數據庫中有哪些DBA用戶? select username from dba_users;
3、查看當前用戶擁有哪些表? select table_name from user_tables;
4、Oracle新建表空間,建立用戶的步驟? A,創建表空間
create tablespace blueskydb datafile 'D:\oracle\product\10.2.0\oradata\bluesky\blueskydb.dbf' size 500m;
B、新建用戶
create user bluesky identified by bluesky;
C、用戶授權
grant resource, connect, RECOVERY_CATALOG_OWNER to bluesky;
grant create table to bluesky;
alter user bluesky quota unlimited on blueskydb;
alter user bluesky default tablespace blueskydb;
D、這樣就可以了,使用SQLPLUS或其他的工具連接試試吧!
