你将不得不给出一个完整的例子，包括create table，因为它看起来对我来说很好:
create table t (
c1 int, c2 int
) partition by list ( c1 ) (
partition p1 values ( 1 ),
partition p2 values ( 2 )
);
create index i
on t ( c2 )
local;
insert into t values ( 1, 1 );
insert into t values ( 2, 2 );
commit;
alter table t truncate partition p1;
select partition_name, status
from user_ind_partitions
where index_name = 'I';
PARTITION_NAME STATUS
P1 USABLE
P2 USABLE
alter index i rebuild partition p1;
select partition_name, status
from user_ind_partitions
where index_name = 'I';
PARTITION_NAME STATUS
P1 USABLE
P2 USABLE
我不确定您为什么要尝试重建索引。因为据我所知，它在截断后仍然有效...
