在修改源SQL时，oracle视图是否正常删除所有授权？ 我正在使用SQL Developer，如果它与它有任何关系。
答案 0 :(得分：6)
首先，你没有＆＃34;拨款＆＃34; - ＆＃34; grant＆＃34;是一项行动。你有＆＃34;角色＆＃34;和＃34;特权＆＃34;。
其次，视图本身既没有角色也没有特权 - 模式确实有。基本上，自我描述性命令是：grant select on view_1 to schema_1。
第三，如果您创建或替换您的视图，架构不会失去其权限。这是一个快速示例：
11:03:07 @> conn system/sys@oars_sandbox
Connected.
11:03:15 SYSTEM@oars_sandbox> create user test1 identified by test1;
User created.
11:03:39 SYSTEM@oars_sandbox> create user test2 identified by test2;
User created.
11:03:48 SYSTEM@oars_sandbox> create view test1.view1 as select * from dual;
View created.
11:04:03 SYSTEM@oars_sandbox> grant select on test1.view1 to test2;
Grant succeeded.
11:04:15 SYSTEM@oars_sandbox> select grantee, owner, table_name, privilege, grantor from dba_tab_privs where grantee = 'TEST2';
GRANTEE OWNER TABLE_NAME PRIVILEGE GRANTOR
------------------------------ ------------------------------ ------------------------------ ---------------------------------------- ------------------------------
TEST2 TEST1 VIEW1 SELECT TEST1
11:05:13 SYSTEM@oars_sandbox> create or replace view test1.view1 as select * from dual;
View created.
11:05:24 SYSTEM@oars_sandbox> select grantee, owner, table_name, privilege, grantor from dba_tab_privs where grantee = 'TEST2';
GRANTEE OWNER TABLE_NAME PRIVILEGE GRANTOR
------------------------------ ------------------------------ ------------------------------ ---------------------------------------- ------------------------------
TEST2 TEST1 VIEW1 SELECT TEST1
但是，SQL开发人员很可能首先调用drop view而不是create or replace。在这种情况下，您的权限会自动删除。
11:05:26 SYSTEM@oars_sandbox> drop view test1.view1;
View dropped.
11:10:21 SYSTEM@oars_sandbox> select grantee, owner, table_name, privilege, grantor from dba_tab_privs where grantee = 'TEST2';
no rows selected
11:10:24 SYSTEM@oars_sandbox> create or replace view test1.view1 as select * from dual;
View created.
11:10:26 SYSTEM@oars_sandbox> select grantee, owner, table_name, privilege, grantor from dba_tab_privs where grantee = 'TEST2';
no rows selected
