oracle 创建中间用户，并授权

1.当前状况 系统正式用户：ecp 开发用户需求：按工号新增用户，开发以后不使用ecp，而使用工号登录，工号用户需要可以查看ecp所有的对象，但是无法进行删除，修改的动作

2.工号用户：BAC7000370 3.权限授予说明 table----select view ----select trigger ---- debug table(trigger 没有单独的权限，因为trigger是依赖在表上面) package ---- execute （execute/debug 权限都可以看到但是无法修改，下同，只有execute权限，无法查看 package body 的内容，需要 debug权限） package body ---- debug package procedure ---- execute type -----execute type body ---- debug type function ---- execute sequence ---- select (可以调用) 以上所有对象权限都可以在 dba_tab_privs 视图里面查找到(trigger除外，检查trigger是否能被看到，只要检查是否有debug table权限即可)

3.执行

select * from dba_tab_privs a where a.owner='ECP';

--如果量少可以手动拼接语句，手动执行
select 'grant select,delete,insert,update,debug on '||a.owner||'.'||a.table_name||' to BAC7000370;' from dba_tables a where a.owner='ECP';
select 'grant execute,debug on '||a.owner||'.'|| a.object_name||' to BAC7000370;' 
from dba_objects a where a.owner='ECP' and a.object_type='PACKAGE';
....
--如果还需要进一步方便，可以创建同义词
select 'CREATE OR REPLACE SYNONYM BAC7000370.'||a.table_name||' for ecp.'||a.table_name||' ;' from dba_tables a where a.owner='ECP';

4.使用存储过程 前提 有部分ecp的对象调用了其他用户的对象，这部分需要提前连带授权

select * from dba_tab_privs a where a.grantee='ECP';
select 'grant '||a.privilege||' on '||a.owner||'.'||a.table_name||' to '||a.grantee||' with grant option;' from dba_tab_privs a where a.grantee='ECP';
--grant select on pcp.VIEW_SCM_AMOUNT to ecp with grant option;
--grant EXECUTE on pcp.DS_FUNC_DECRYPT_DES to ecp with grant option;

create or replace noneditionable procedure dba_grant_user(var_username in varchar2,var_gonghao in varchar2)
as
num number;
v_table_sql varchar2(4000) ;
--v_table_debug_sql varchar2(4000) ;
v_view_sql varchar2(4000) ;
v_procedure_sql varchar2(4000) ;
v_type_sql varchar2(4000) ;
--v_type_body_sql varchar2(4000) ;
v_function_sql varchar2(4000) ;
v_package_sql varchar2(4000) ;
--v_package_body_sql varchar2(4000) ;

说明： 1.因为很多对象都是sys用户的，用system建procedure不方便，需要授权一堆，因此，如果想要system执行，可用sys建立，授权给system执行权限即可，不是system能查到这些视图，就能建立存储过程 grant execute ,debug on sys.dba_grant_user to system;

2.因为有些用户的对象特别的，所以调用时加上dbms_output.enable(buffer_size => null)，不然会报错，PLSQL放不下 begin dbms_output.enable(buffer_size => null);

3.v_table_sql := 'grant select,delete,update,insert,debug on "'||var_username||'"."' || i.OBJECT_NAME|| '" to "'||var_gonghao||'"'; 最后是故意没有分号，有分号执行报错，没有分号才行，和拼接语句再执行不太一样，原因不太了解
