1）查看用户的默认表空间及临时表空间
set lines 300
col username for a30
select username ,default_tablespace,TEMPORARY_TABLESPACE from dba_users where username='MESPRD';
-----------------------------------
USERNAME DEFAULT_TABLESPACE TEMPORAR Y_TABLESPACE
MESPRD HTTBS_MESPRD TEMP
2)查看该用户的权限和角色
select privilege from dba_sys_privs where grantee='SYSADM'
union
select privilege from dba_sys_privs where grantee in (select granted_role from dba_role_privs where grantee='MESPRD' );
-----------------------------------
PRIVILEGE
CREATE CLUSTER
CREATE INDEXTYPE
CREATE OPERATOR
CREATE PROCEDURE
CREATE SEQUENCE
CREATE SESSION
CREATE TABLE
CREATE TRIGGER
CREATE TYPE
已选择9行。
3)获取获得授予用户权限的脚本
select 'grant '||privilege||' to SYSADM;' from (select privilege from dba_sys_privs where grantee='SYSADM'
union
select privilege from dba_sys_privs where grantee in (select granted_role from dba_role_privs where grantee='SYSADM' ));
4）执行脚本获得删除该schema下对象的脚本 mesprd为要删除的schema
connect mesprd/MESPRD
spool E:\app\Administrator\del_mesprd.sql;
select 'alter table '||table_name||' drop constraint '||constraint_name||' ;' from user_constraints where constraint_type='R';
select 'truncate table '||table_name ||';' from user_tables;
select 'drop table '||table_name ||' purge;' from user_tables;
select 'drop index '||index_name ||';' from user_indexes;
select 'drop view ' ||view_name||';' from user_views;
select 'drop sequence ' ||sequence_name||';' from user_sequences;
select 'drop function ' ||object_name||';' from user_objects where object_type='FUNCTION';
select 'drop procedure '||object_name||';' from user_objects where object_type='PROCEDURE';
select 'drop package '|| object_name||';' from user_objects where object_type='PACKAGE';
select 'drop database link '|| object_name||';' from user_objects where object_type='DATABASE LINK';
spool off;
5）sqlplus连接到该schema下，执行如上获得的脚本
执行前查看下该schema下的对象，执行后再次查看下该schema下的对象
@？\E:\app\Administrator\del_mesprd.sql;
SQL> select object_type,count(*) from user_objects group by object_type;
6）kill掉连接数据库的session
select 'alter system kill session '''||sid||','||serial#||''' immediate;' from v$session where username='MESPRD';
7）删除该schema
drop user MESPRD cascade;
