How to store time from java.util.Date into java.sql.Date

Question

I want to convert java.util.Date to java.sql.Date but I want hours, minutes, and seconds as well but java.sql.Date can be used only to store date(n

Answer 1

As other folks said, you need to use java.sql.TimeStamp.

public class Test {
        public static void main(String[] args) {
            java.util.Date date = new java.util.Date();
            java.sql.Timestamp sqlTimeStamp = new java.sql.Timestamp(date.getTime());
            System.out.println("util-date:" + date);
            System.out.println("sql-timestamp:" + sqlTimeStamp );

        }

}

Answer 2

The java.sql.Date type is used to store only date (no time) information, as it maps to the SQL DATE type, which doesn't store time. What its toString() method does is:

Formats a date in the date escape format yyyy-mm-dd.

To achieve the desired output you can use java.sql.Timestamp, which stores date and time information, mapping to the SQL TIMESTAMP type. Its toString() method outputs what you need:

Formats a timestamp in JDBC timestamp escape format: yyyy-mm-dd hh:mm:ss.fffffffff, where ffffffffff indicates nanoseconds.

Example:

java.text.DateFormat format = new java.text.SimpleDateFormat("yyyyMMddHHmmss");
java.util.Date date = format.parse("20110210120534");
java.sql.Timestamp timestamp = new java.sql.Timestamp(date.getTime());
System.out.println(timestamp); // prints "2011-02-10 12:05:34.0"
