Query to get rows based on dates from two table in Athena - sql

Question

I have two table called master_tbl and anom_table
as follows:
master_tbl
date id country value
2017-01-01 26 US 2
2017-01-02 26 US 4
2017-01-03 26 US 9
2017-01-04 26 US 2
2017-01-05 26 US 4
2017-01-06 26 US 1
2017-01-07 26 US 5
2017-01-08 26 US 3
2017-01-09 26 US 100
2017-01-10 26 US 4
anom_tbl
date id country anoms
2017-01-01 26 US 0
2017-01-02 26 US 0
2017-01-03 26 US 9
2017-01-04 26 US 0
2017-01-05 26 US 0
2017-01-06 26 US 0

2017-01-08 26 US 0
2017-01-09 26 US 100
2017-01-10 26 US 0
I want to create third table from master_tbl and join with anom_tbl to select only rows which dates that has value in anom column in from anom_tbl and one day before and one day after that date from master_tbl
Finally I want to have the following table
date id country value
2017-01-02 26 US 2
2017-01-03 26 US 9
2017-01-04 26 US 4
2017-01-08 26 US 3
2017-01-09 26 US 100
2017-01-10 26 US 4
because I have big data I takes time that I run it in R or python then I want to create table in AWS (athena)
I have tried the following code in the athena however it does not work
FROM
(SELECT t2.value,
t1.id,
t1.country AS country,
cast(t1.date AS DATE) AS orig_date
FROM
(SELECT id,
country,
date
FROM anom_tbl) t1
JOIN master_tbl t2
ON t2.id=t1.id
AND t2.country= t1.country
AND t2.date=t1.date) t3
JOIN master_tbl t2
ON t3.id=t2.id
AND t3.country=t2.country
where t2.date IN(GETDATE()-1)
Could you please help me to modify the sql code to get the proper result.

Answer 1

If I followed you correctly, you could do this with exists:
select m.*
from master_tbl m
where exists (
select 1
from anom_tbl a
where
a.anoms <> 0
and a.id = m.id
and a.country = m.country
and m.date >= a.date - interval '1' day
and m.date <= a.date + interval '1' day
)
This brings all records in the master table for which another record exists in the anom table for the same id and country, with a non-0 value, within a +/- 1 day interval.
