If the function names are in upper case, the query fails. For example:

where voter_id=10;

| 2003-07-09T00:00:00.000-07:00 |

Same query with function name in uppercase:
select TO_DATE('2003/07/09', 'yyyy/MM/dd') from voter where voter_id=10;
message: "Failure while parsing sql. < ValidationException:[
