Halo数据库大师，来自印度尼西亚的问候

我目前正在努力将我的公司大表从非分区迁移到分区表。每次我尝试使用insert插入日志中的journal1 select *时，插入到journal1中的数据不会被分区。任何线索？

这里是非分区表作为数据源。

这是我用来迁移数据的脚本

insert into journal1
select * from journal

当我检查表journal1中的数据时，数据插入成功但没有分区。任何人都有线索为什么会这样？

Answer 1

DBA_TABLES.NUM_ROWS是收集优化程序统计信息时计算的行数。它不一定代表实际的行数。不管在表中插入的内容，在收集统计信息之前，查询将如下所示：

select partition_name, num_rows
from dba_tab_partitions
where table_name = 'JOURNAL1';

PARTITION_NAME  NUM_ROWS
--------------  --------
PART1   
PART2   
PART3   
PART4   
PART5

收集统计信息将设置行数，但数字不会保持最新：

begin
    dbms_stats.gather_table_stats('PRODBMDB', 'JOURNAL1');
end;
/

select partition_name, num_rows
from dba_tab_partitions
where table_name = 'JOURNAL1';

PARTITION_NAME  NUM_ROWS
--------------  --------
PART1                  0
PART2                  0
PART3                  0
PART4                  0
PART5                  0
