------------------------------------

             Summary: HPL/SQL can not SELECT Date and Timestamp type value into variable 
                 Key: HIVE-21453
                 URL: https://issues.apache.org/jira/browse/HIVE-21453
             Project: Hive
          Issue Type: Bug
          Components: hpl/sql
    Affects Versions: 3.1.1
         Environment: Centos 7.1, Hive 3.1.1
            Reporter: DingQiang Liu
            Assignee: DingQiang Liu


HPL/SQL forgot Date and Timestamp types when SELECT INTO variables. for example, current implement will set  null, not correct value, to variables for following case,  select_into3.sql:

 declare v_date date;
 declare v_timestamp timestamp(17, 3); 

select
   cast('2019-02-20 12:23:45.678' as date),
   cast('2019-02-20 12:23:45.678' as timestamp)
 into
   v_date,
   v_timestamp
 from src limit 1;

print 'date: ' || v_date;
 print 'timestamp: ' || v_timestamp;

The result when running :  bin/hplsql -f select_into3.sql --trace
