在Oracle9i之前,如果你想要把对象权限授予某些用户,那么你需要使用该对象属主或者使用具有该对象with grant option权限的用户。
很多时候你可能需要进行批量授权,那么DBMS_SYS_SQL包可以为你提供简便.
以下过程供参考:
declare
sqltext varchar2(200);
c integer;
begin
for userlist in (select user_id,username from all_users where username not in ('SYS','SYSTEM','EYGLE')) loop
for tablelist in (select owner,table_name from dba_tables where owner = userlist.username) loop
sqltext := 'grant all on '||tablelist.owner||'.'||tablelist.table_name ||' to eygle with grant option';
c := sys.dbms_sys_sql.open_cursor();
sys.dbms_sys_sql.parse_as_user( c,sqltext,dbms_sql.native,userlist.user_id);
sys.dbms_sys_sql.close_cursor(c);
end loop;
end loop;
end;

以下是817中的执行过程,供参考:
SQL> declare
2 sqltext varchar2(200);
3 c integer;
4 begin
5 for userlist in (select user_id,username from all_users where username not in ('SYS','SYSTEM','EYGLE')) loop
6 for tablelist in (select owner,table_name from dba_tables where owner = userlist.username) loop
7 sqltext := 'grant all on '||tablelist.owner||'.'||tablelist.table_name ||' to eygle with grant option';
8 c := sys.dbms_sys_sql.open_cursor();
9 sys.dbms_sys_sql.parse_as_user( c,sqltext,dbms_sql.native,userlist.user_id);
10 sys.dbms_sys_sql.close_cursor(c);
11 end loop;
12 end loop;
13 end;
