在嵌套分区表的静态分区中添加动态分区？

Question

I have a table that has nested partitions like -

• country1
  • run date 1
  • run date 2
• country2
  • run date 1
  • run date 2

I need to add the first layer(country) statically (as they are in different locations) but want the 2nd layer(run dates) to be added dynamically.

I have tried below but its not working-

ALTER TABLE <table_name> ADD PARTITION (country=country1, run_date) LOCATION '<path>';

Answer 1

I don't think there is dynamic partition option in alter table for hive.

However what I understand from your requirement may be something like below.

insert into nested_part partition(country='count1',run_date) select name,id,run_date from source4_nesting where country='count1';
