I have an issue where querying Oracle 9 DB using DB connect. All fields that are varchar returned as empty, but for numeric or date it is returning correcting.    Say if I run on SQL explorer "Select sysdate from dual" or "select count(*) from table_A" I will get the expected result, but running "select transactionid from table_a;" it will return multiple rows  of empty data.    And if I run "select sysdate, transactionid from table_a;" I will get sysdate correctly but transactionid field as empty.    I try to added as input, but when I check the events all the varchar fields does not exists in the events.  Using "select sysdate, transactionid from table_a;", I can see sysdate in the event but not transactionid.    if I run the query in SQL developer it is all working perfectly fine. For other DB input I am using, I don't have this issue. I have trying add the query as input, cast the varchar fields but nothing seems to work. Just wonder if anyone has any ideas how could I work around this?    Below is the information of DB and Splunk: DB is Oracle - Version: 9.2.0.8.0 Splunk Version: 7.2.5 Current Application: Splunk DB Connect App Version 3.1.3 ...
