Datetime vs Date format

[axl169]

I am trying to create a sql with prompts on a DATETIME field, however, I want to convert to just to be able to handle just date. I don't want users to have to enter in the hour and min when the prompt appears. Is there some kind of expression I can create that will convert "12/02/06" to "12/02/06 12:00AM". Thank you in advance.

SELECT A.AN_MT_ID, A.DESCR, A.AN_MT_MODULE, B.OPRDEFNDESC, A.AN_MT_STATUS, TO_CHAR(A.CREATED_DTTM,'YYYY-MM-DD-HH24.MI.SS."000000"'), TO_CHAR(A.DTTM_CLOSED,'YYYY-MM-DD-HH24.MI.SS."000000"'), C.OPRDEFNDESC, TO_CHAR(A.COMPLETION_DATE,'YYYY-MM-DD')
FROM PS_AN_MT_HDR A, PSOPRDEFN B, PSOPRDEFN C, PS_AN_MT_ASSIGN_TO D
WHERE A.CONTACT_ID = B.OPRID
AND D.AN_MT_ID = A.AN_MT_ID
AND D.ASSIGNED_TO = C.OPRID
AND A.AN_MT_STATUS = :1
AND A.DTTM_CLOSED > TO_DATE(SUBSTR(:2, 0, 19),'YYYY-MM-DD-HH24.MI.SS')

Exactly what do you want to convert and at which point.
Do you want to do an UPDATE query on the existing data, converting all the datetimes to the same date with 12am as time. Do you want convert the user input before it enters the database. Etc.
