检查索引情况：

SELECT index_name, column_name, descend,COLUMN_POSITION

FROM user_ind_columns  WHERE

table_name = 'AAA_DATA';

SELECT index_name, column_name, descend,COLUMN_POSITION

FROM user_ind_columns  WHERE

SELECT index_name, column_name, descend,COLUMN_POSITION

select table_name,index_name,status,blevel,leaf_blocks from

user_Indexes where table_name

in('AAA_DATA','IPTV_HW_DATA','IPTV_ZTE_DATA');

查看表占用：

select segment_name,sum(bytes)/1024/1024/1024 from

user_segments where segment_name

in('AAA_DATA','IPTV_HW_DATA','IPTV_ZTE_DATA') group by

segment_name;

查看分区数：

select table_name,partition_name from user_tab_partitions

select count(*) from IPTV_ZTE_DATA partition(ZTE_P1);
