3.2.4、查看数据
?
查看分区数据
select * from LST_RNG_LIST partition(P_3512860010); select * from LST_RNG_LIST partition(P_3512860005); select * from LST_RNG_LIST subpartition(P_3512860010_SP_20150726); select * from LST_RNG_LIST subpartition(P_3512834993_SP_20150802);
收集分区统计信息
begin
dbms_stats.gather_table_stats(ownname=>'WKOD_VERIFY',granularity =>'all',tabname=>'LST_RNG_LIST',cascade=>true);
end;
?
查看主分组
select partition_position,table_name,partition_name,high_value,tablespace_name,num_rows
from user_tab_partitions
where table_name='LST_RNG_LIST';
num_rows=5，LST_PNG_LIST表分别在两个表空间中有5条数据
?
查看子分区
select subpartition_position,table_name,partition_name,subpartition_name,high_value,tablespace_name,num_rows
from user_tab_subpartitions
where table_name='LST_RNG_LIST';
3.2.5、追加分区
?
方式一：追加主分区
alter table LST_RNG_LIST add partitionP_3512834993 values ('3512834993') tablespace TS_3512834993
查看分区
select partition_position,table_name,partition_name,high_value,tablespace_name,num_rows
from user_tab_partitions
where table_name='LST_RNG_LIST';
?
查看子分区
select subpartition_position,table_name,partition_name,subpartition_name,high_value,tablespace_name,num_rows
from user_tab_subpartitions
where table_name='LST_RNG_LIST';
默认按照表创建时子分区的的分区规则，自动生成两个子分区（红色框内）
?
删除添加的List分区
alter table LST_RNG_LIST drop partitionP_3512834993;
对应的子分区会自动被drop掉。?
方式二：追加主分区及其子分区
alter table LST_RNG_LIST add partition P_3512834993 values ('3512
