Converting long value column into date using sql query itself. Oracle, 9i

In oracle db I have a column with integer data type, the actual content is milliseconds of date. I required a sql query which converts those milliseconds value into date value. For example, the value in the column is 1225825655, and required value should be in the form of 'mm/dd/yyyy'. I going to use this query in the iReport, so the modification is required in the query itself.

what are the milliseconds in reference to?  They must be a counter from some point in time



Assuming the standard "epoch" of 1970-01-01 00:00:00

TO_CHAR(TO_DATE('1970-01-01', 'yyyy-mm-dd') + 1225825655 / 86400000, 'mm/dd/yyyy')

If Jan 1, 1970 is not your base, then substitute whatever date is your base time you count from.

are you sure your counter is in milliseconds?

1225825655  would only be January 15, 1970

if you counter is in seconds then 1225825655  would be November 4, 2008.


again, assuming Jan 1, 1970 as your base date

so, if your counter is actually seconds rather than milliseconds then use


TO_CHAR(TO_DATE('1970-01-01', 'yyyy-mm-dd') + 1225825655 / 86400, 'mm/dd/yyyy')

Hi sdstuber,
You are correct the values are in seconds,  I used the divide by 86400.
Thanks.

Why the penalty B?  If you needed further help you only needed to ask.

Please don't assign penalties without giving the volunteers (not just me) a chance to complete your answer.
