Hive查询不返回输出

Question

Hive query is not returning the data (0 number of rows).

need to retrieve 1 month back records from till/current date from the table.

select * from table1 
where date_format(order_date,'yyyy-MM-dd') >= date_format(add_months(current_date,-1),'yyyy-MM-01')
and date_format(order_date,'yyyy-MM-dd') <= date_format(current_date,'yyyy-MM-dd');

need to retrieve past 1 month data to till date.

Answer 1

I think, you can use "BETWEEN". Because you work between two dates and maybe more than performances

SELECT *
  FROM your_table
  WHERE your_date_column BETWEEN '2018-09-01' AND '2019-06-01';

Answer 2

Adding to the previous answer, the following is the code which you should definitely be trying out

The DATE_SUB function in hive allows you to subtract dates by integers, thus 30 in our case denotes a month**

To cast your strings to dates, you may use TO_DATE() or DATE() functions.

** definition of a month varies with your use case. In this case, we are considering a 30 days gap as a month. If your use case requires calendar months to be considered as a month, use add_months function instead

         SELECT columns 
            from TABLE_NAME 
            WHERE YOUR_DATE_COLUMN_NAME 
                  BETWEEN DATE(CURRENT_DATE) AND DATE_SUB(CURRENT_DATE, 30)
