How do I change a long variable to a Timestamp variable? I can convert it to a String but I need to convert it to Timestamp in order to use it in a database.
I don't know Java, but an internet search suggests that Timestamp has a constructor which takes a long:
Timestamp
long
So, you can do something like this, perhaps:
Timestamp t = new Timestamp(l);
