amazon athena create request with partitions - sql

Question

I create a table with partitions as follow : first by year, month, and day.
Question : I hope get data of 12/2017 and 03/2018, how I can do this?
What I think do :
where (year='2017' and month='12') and ( year ='2018' and month='03')
Is it correct? I will not have a confusion so Amazon Athena get data of:
12/2017 and 03/2018 and 03/2017 and 12/2018
because of the and operator ?
PS: I can't test, I have only free account.
Thanks.

Answer 1

Anyway, I tried in a mini set of data and I found that Amazon Athena take into account the parenthesis.
My test is as follow :
The DDl of table as générated :
CREATE EXTERNAL TABLE `manyands`(
`years` int COMMENT 'from deserializer',
`months` int COMMENT 'from deserializer',
`days` int COMMENT 'from deserializer')
PARTITIONED BY (
`year` string,
`month` string)
ROW FORMAT SERDE
'org.openx.data.jsonserde.JsonSerDe'
STORED AS INPUTFORMAT
'org.apache.hadoop.mapred.TextInputFormat'
OUTPUTFORMAT
'org.apache.hadoop.hive.ql.io.IgnoreKeyTextOutputFormat'
LOCATION
's3://mybucket/'
My set of data test:
My tests:
1- SELECT * FROM "atlasdatabase"."manyands" where month='1';
I got in CSV format :
"years","months","days","year","month"
"2017","1","21","2017","1"
"2018","1","81","2018","1"
2- SELECT * FROM "atlasdatabase"."manyands" where month='1' and year='2017';
"years","months","days","year","month"
"2017","1","21","2017","1"
3- SELECT * FROM "atlasdatabase"."manyands" where (month='1' and year='2018') and (month='3' and year='2017') ;
empty (Zéro enregistrements renvoyés)
4- SELECT * FROM "atlasdatabase"."manyands" where (month='1' and year='2018') or (month='3' ) ;
"years","months","days","year","month"
"2018","1","81","2018","1"
"2017","3","73","2017","3"
"2018","3","73","2018","3"
Conclusion : add OR operator between many instances of the partitions.
