Subject [jira] [Updated] (HIVE-15728) Empty table returns result when querying partitioned field with a function
Date Thu, 26 Jan 2017 13:26:24 GMT

     [ https://issues.apache.org/jira/browse/HIVE-15728?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jared Leable updated HIVE-15728:
--------------------------------
    Description: 
If a partitioned table contained data and is then truncated a query will still return a result
when using a function on a partitioned field.

create table test1 (
	field string
)
partitioned by(dt string);

set hive.exec.dynamic.partition.mode=nonstrict;
insert into test1 
partition(dt)
select 'a','2017-01-01';

-- to view inserted records
select * from test1;

-- to delete all records from the table
truncate table test1;

-- to view 0 records in the table
select * from test1;

-- still returns a result of '2017-01-01'
select max(dt) from test1;
