Question

有人知道为什么Oracle（使用12c）在编辑策略在分区表上然后 alter table ... truncate partion .. update global indexes 运行时会抛出错误？事实上，更新全局索引正在抛出异常。

我可以通过添加异常处理程序并运行一个删除语句来轻松解决这个问题。它只是慢得多。

测试用例：

drop table test;

create table test (
  f1 number,
  f2 number,
  constraint pk_test primary key (f1)
)
partition by list (f1) (
  partition dim_0 values (0),
  partition dim_1 values (1),
  partition dim_2 values (2),
  partition dim_3 values (3),
  partition dim_4 values (4),
  partition dim_5 values (5)
);


insert into test (f1, f2)
with r(f1, f2) as (
  select 1, 2 from dual
  union all
  select f1+1, f2+2 from r
  where f1<5
)
select f1, f2
from r;

-- select the data, without redaction
select *
from test;

-- add a redaction policy to the table
begin
  dbms_redact.add_policy(
    object_schema        => 'HPF',
    object_name          => 'test',
    column_name          => 'f1',
    policy_name          => 'hide_f1',
    function_type        => dbms_redact.full,
    function_parameters  => dbms_redact.redact_us_ssn_f5,
    expression           => '1=1'
  );
end;
/

-- select the data, with redaction
select *
from test;

-- trunacte test
alter table test truncate partition dim_5 update global indexes;
-- drop test
alter table test drop partition dim_5 update global indexes;


--============> OUTPUT:

5 rows inserted.
