> 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
> Configuration file: file:/hive/conf/hplsql-site.xml
