阿里云odps循环删除分区

 

阿里云环境下，循环删除分区操作，通过pyodps实现：

我的分区字段是dt，类型是bigint

t = o.get_table('tmp_activity_push')
for a in range(20190501,20190530):
    date = 'dt =' + str(a)
    print(date)
    t.delete_partition(date, if_exists=True) # 存在的时候才删除

//改进版
import datetime

def dateRange(beginDate, endDate):
    dates = []
    dt = datetime.datetime.strptime(beginDate, "%Y%m%d")
    date = beginDate[:]
    while date <= endDate:
        dates.append(date)
        dt = dt + datetime.timedelta(1)
        date = dt.strftime("%Y%m%d")
    return dates

t = o.get_table('main_recommend_style_feature_data_byday')

for a in dateRange('20210324','20210610'):
    date = 'dt =' + str(a)
    print(date)
    t.delete_partition(date, if_exists=True) # 存在的时候才删除
