ORACLE迁移中的一些经验（三）批量导出index 建索引、用户、权限等语句

1、批量导出INDEXES语句

SELECT DBMS_METADATA.GET_DDL(u.OBJECT_TYPE, u.object_name,u.OWNER)
FROM DBA_OBJECTS u
where u.OBJECT_TYPE='INDEX' AND u.owner in('TONY');

导出语句时需要格式化，方便使用。

set linesize 180
set pages 999
set long 90000

--设置按单词换行
col a for a200 wrapped word

--去除storage等多余参数
EXECUTE DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'STORAGE',FALSE);
--输出信息采用缩排或换行格式化
EXECUTE DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'PRETTY',true);
--确保每个语句都带分号
EXECUTE DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'SQLTERMINATOR',true);

2、-- 创建用户脚本
set serveroutput on
set line 100
set pagesize 0
declare
cursor c1 is select username from dba_users a where a.account_status='OPEN' ;
v_user c1%rowtype;
begin
open c1;
loop
fetch c1 into v_user ;
exit when c1%notfound;
DBMS_OUTPUT.put_line(to_char(dbms_metadata.get_ddl('USER',v_user.username))||';');
end loop;
close c1;
end;
/

3、---授权系统权限脚本
select 'grant '||t.privilege ||' to '||t.grantee || decode(t.admin_option,'YES',' with admin;',';')
from dba_sys_privs t
where t.grantee not in
('SPATIAL_WFS_ADMIN_USR',
'DIP'
);

4、--授角色脚本
select 'grant '||granted_role||' to '||grantee||';' from dba_role_privs
where grantee not in
('SPATIAL_WFS_ADMIN_USR',
'DIP',
'MDDATA'
);

5、-- 表权限
select 'grant '||t.privilege||' on '||t.grantor||'.'||t.table_name||' to '||t.grantee||decode(t.grantable,'YES',' with grant;',';')
from dba_tab_privs t
where t.grantor not in
('SYS','SYSTEM','DBSNMP','PERFSTAT','OUTLN','WMSYS','CONNECT','DBA',
'EXP_FULL_DATABASE','IMP_FULL_DATABASE','OEM_MONITOR','RESOURCE','JAVADEBUGPRIV')
order by t.grantee
