continuously DB query with overcome short date format

[OBsecurity]

Hello,
im trying querying HIVE table via 'rising' mode.
query must contain certain timestamp_1 column (otherwise no results are back - massive data)
and must be rising method since results must be real-time.
Unfortunately timestamp column represented with yyyy-MM-dd format only (e.g 2018-01-04) - therefore cannot query real-time.
Table also include bigint date column, i was trying:
1. casting it to readable timestamp - no good.
2. using bigint column as 'rising' - no good.
all of this because timestamp_1 wasnt part of where clause.

• im using splunk dbx.

any ideas? work arounds?

thanks!
