Hive 如果连续行之间的差异小于10天，则生成排名/编号,hive,Hive,需要配置单元查询来计算连续记录的日期差异，但对于相同的txn类型，如果差异小于10，则生成相同的编号，否则生成新编号 with test_data as ( SELECT 1 txn_id, 'T100' txn_type, to_date('26-AUG-2015','DD-MON-YYYY') txn_date from dual union all SELECT 2 txn_id, 'T100', to_date('03-NOV-2015','DD-MON-YYYY') from du

输入表预期产量

使用公共表表达式标记差异超过10天的行，然后对这些行进行计数以获得新的数字

with test_data as (
 SELECT 1 txn_id, 'T100' txn_type, to_date('26-AUG-2015','DD-MON-YYYY') txn_date from dual union all
 SELECT 2 txn_id, 'T100', to_date('03-NOV-2015','DD-MON-YYYY') from dual union all
 SELECT 3 txn_id, 'T100', to_date('05-DEC-2015','DD-MON-YYYY') from dual union all
 SELECT 4 txn_id, 'T100', to_date('08-DEC-2015','DD-MON-YYYY') from dual union all
 SELECT 5 txn_id, 'T100', to_date('25-JAN-2016','DD-MON-YYYY') from dual union all
 SELECT 6 txn_id, 'T111', to_date('26-JAN-2016','DD-MON-YYYY') from dual union all
 SELECT 7 txn_id, 'T200', to_date('02-FEB-2016','DD-MON-YYYY') from dual union all

           over ( partition by txn_type order by txn_id ), td.txn_date-9999) > 10 
           THEN 'Y' ELSE NULL end new_txn_marker from test_data td )
SELECT txn_id, txn_type,txn_date, 
       count(new_txn_marker) over ( partition by txn_type order by txn_id ) "NUMBER"

不确定少于10天是否意味着严格或非严格不平等，但除此之外：

我使用number_uu作为列名；不要使用Oracle保留字作为表名或列名，除非你的生命取决于它，即使如此。

这里面有什么问题吗？也许你应该去看看如果你想得到答案，你得问个问题。。。。如果你要我们写你的代码。所以不批准，所以是为了帮助找到原因并修复代码中的问题。在为发布的需求编写代码时，您忘记添加解释问题的部分。使用option更新您的问题，使其包含遗漏的部分。@Pshemo但这个问题确实很有趣。我仍然想不出它是如何通过OracleAccess实现的。什么是access查询？你的意思是微软访问？
