Question

Is it possible that date stored in database table change automatically ???

Answer 1

If we understood your question correctly, than the answer is yes. Values in table can depend on time, date, or any other figures retrieved from any source
(usually internet, such as currency rates, etc.). Values in table can be than
calculated in some predefined way and then recalculated on data from source
changes.
If you meant something other, feel free to ask.
