Adding hours, minutes, seconds to SQL Date

Question

Good Day!

I have a problem with SQL Dates. I think the main problem is on the perspective of time. In my program, I have a start and end date, say for example

Answer 1

This is the code for timestamp datatype

Date d=new Date();
Timestamp t=new Timestamp(d.getTime());try{
PreparedStatement pt=con.prepareStatement("INSERT INTO survey_schedule (start_date) VALUES (?);");
pt.setTimestamp(1, start_date);

pt.executeUpdate();}
catch(Exception e)
{
    System.out.println(e);
}

This is an example that will store the date and time in the mysql database
