As the title suggests, I'm simply trying to get the result set between midnight today and right now. So given the time of this post, I want data between 06/30/16 00:00:00 and 06/30/16 15:52:00. Why does the below query not return anything? Thanks.
SELECT * FROM tableName
WHERE event_date >= TO_DATE(TRUNC(SYSDATE) || ' 00:00:00', 'DD-MON-YY HH24:MI:SS')
AND event_date <= TO_DATE(TRUNC(SYSDATE))
