> 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
