I need to include a field date in the primary of a table. But when I try to insert new record with the same date but different time of the day, I get an
error message "Unique constraint violated".
How can I handle this ?

Oracle will only see it as being unique if the date&time is identical (down to to seconds which is the highest precision supported). Examine your existing data...
select to_char(date_col, 'dd-mon-yyyy hh24:mi:ss')...
if you are using date pictures, ensure that you are using hh24. If you are using hh, then you need to use am/pm too.0 Also use mi for minutes not mm (months)
