insert into range_part_mult_col_tab (id,deal_date,area_code,nbr,contents)
select rownum,
to_date( to_char(sysdate-365,'J')+TRUNC(DBMS_RANDOM.VALUE(0,365)),'J'),

该表是否是分区表，分区表的分区类型是什么，是否有子分区，分区总数有多少：
该分区表在哪一列上建分区,有无多列联合建分区:
select column_name, object_type, column_position from user_part_key_columns where name ='RANGE_PART_MULT_COL_TAB';
该分区表有多大:
select sum(bytes) / 1024 / 1024 from user_segments where segment_name ='RANGE_PART_MULT_COL_TAB';
该分区表各分区分别有多大，各个分区名是什么:
select partition_name, segment_type, bytes from user_segments where segment_name ='RANGE_PART_MULT_COL_TAB';
该分区表的统计信息收集情况:
select table_name, partition_name, last_analyzed, partition_position, num_rows from user_tab_statistics t where table_name ='RANGE_PART_MULT_COL_TAB';
该分区表有无索引，分别什么类型,全局索引是否失效，此外还可看统计信息收集情况:
select table_name,
index_name,
last_analyzed,
blevel,
num_rows,
leaf_blocks,
distinct_keys,
status
from user_indexes
where table_name ='RANGE_PART_MULT_COL_TAB';
分区表在哪些列上建了索引:
select index_name, column_name, column_position from user_ind_columns where table_name = 'RANGE_PART_MULT_COL_TAB';
该分区表上的各索引分别有多大：
select segment_name,segment_type,sum(bytes)/1024/1024
from user_segments
where segment_name in
(select index_name
from user_indexes
where table_name ='RANGE_PART_MULT_COL_TAB'
)
group by segment_name,segment_type ;
该分区表的索引段的分配情况：
select segment_name
partition_name,
segment_type,
bytes
from user_segments
where segment_name in
(select index_name
from user_indexes
where table_name ='RANGE_PART_MULT_COL_TAB');
