删除HIVE中的一系列分区

Question

我有一个Hive(版本0.11.0)表,按列日期分区,类型为字符串.我想知道在Hive中是否存在一种方法,我可以通过该方式删除一系列日期的分区(例如从'date1'到'date2').我尝试了以下(SQL类型)查询,但它们似乎在语法上不正确:

ALTER TABLE myTable DROP IF EXISTS PARTITION
(date>='date1' and date<='date2');

ALTER TABLE myTable DROP IF EXISTS PARTITION
(date>='date1' && date<='date2');

ALTER TABLE myTable DROP IF EXISTS PARTITION
(date between 'date1' and 'date2');

Answer 1

我尝试了这种语法，它起作用了。

ALTER TABLE mytable DROP PARTITION (dates>'2018-04-14',dates<'2018-04-16');

命令输出：

    Dropped the partition dates=2018-04-15/country_id=107
    Dropped the partition dates=2018-04-15/country_id=110
    Dropped the partition dates=2018-04-15/country_id=112
    Dropped the partition dates=2018-04-15/country_id=14
    Dropped the partition dates=2018-04-15/country_id=157
    Dropped the partition dates=2018-04-15/country_id=159
    Dropped the partition dates=2018-04-15/country_id=177
    Dropped the partition dates=2018-04-15/country_id=208
    Dropped the partition dates=2018-04-15/country_id=22
    Dropped the partition dates=2018-04-15/country_id=233
    Dropped the partition dates=2018-04-15/country_id=234
    Dropped the partition dates=2018-04-15/country_id=76
    Dropped the partition dates=2018-04-15/country_id=83
