Question

我想在oracle中写一行，以便可以一次将表的选择特权授予多个模式。

这是我所拥有的，但是出现语法错误：

GRANT SELECT ON OWNER.TABLE_NAME to (select distinct owner from dba_objects where owner like 'SCHEMA_%');

您需要动态SQL来做到这一点，例如

SQL> declare
  2    l_str varchar2(200);
  3  begin
  4    for cur_r in (select 'MIKE' username from dual union all
  5                  select 'IMPORTER'      from dual union all
  6                  select 'DIP'           from dual
  7                 )
  8    loop
  9      l_str := 'grant select on emp to ' || cur_r.username;
 10      dbms_output.put_line(l_str);
 11      execute immediate l_str;
 12    end loop;
 13  end;
 14  /
grant select on emp to MIKE
grant select on emp to IMPORTER
grant select on emp to DIP

PL/SQL procedure successfully completed.

我使用数据库中的多个用户在游标FOR循环中获取用户名；您可以用自己的select distinct owner from dba_objects where owner like 'SCHEMA_%'代替它。
