我们可以在 HIVE 中为 BIGINT 列设置空值吗

Question

I have a question , probably a basic one . I would like to give null value to a column whose data type BIGINT . Is that possible?

Answer 1

Yes it's possible and easy to check:

1. hive> create table test_null_bigint(col bigint);
2. insert into table test_null_bigint values(null);
3. hive> select * from test_null_bigint;

OK

NULL

Answer 2

According to the Apache Hive documentation , you should be able to simply leave the value empty.:

Missing values are represented by the special value NULL.
