Re: how to change dates or times in a oracle date time field

I think he realizes that Daniel..the question is how to add time to a date field..

Jim,
To do that you simply add an integer to the field....the integer represents the number of DAYS..so,

SYSDATE + 3 will add three days to SYSDATE, SYSDATE - 3 subtracts three days etc...

To get hours, minutes, seconds etc you divide a day into it's components (24 hours in a day for instance) so,

SYSDATE + 1/24 adds an hour, SYSDATE + 1/24/60 adds a minute etc..

Therefore to add 8 minutes as in your example you would use SYSDATE + 8/24/60

I hope this helps,

Steve
