How can we set time in a table in JDBC?

You can insert time values in SQL using the time datatype, The java.sql.Time class maps to the SQL Time type.

The PreparedStatement interface provides a method named setTime(). Using this you can insert time into a table. This method accepts two parameters −

• An integer representing the parameter index of the place holder (?) to which we need to set date value.

• A Time object representing the time value to be passed. The constructor of java.sql.Time class accepts a variable of long type representing the number of milliseconds from the epoch (standard base time I.e. January 1, 1970, 00:00:00 GMT).

Example

Assume we have created a table named Dispatches in MySQL database with the following description −

+------------------+--------------+------+-----+---------+-------+
| Field            | Type         | Null | Key | Default | Extra |
+------------------+--------------+------+-----+---------+-------+
| Product_Name     | varchar(255) | YES  |     | NULL    |       |
| Date_Of_Dispatch | date         | YES  |     | NULL    |       |
| Time_Of_Dispatch | time         | YES  |     | NULL    |       |
| Location         | varchar(255) | YES  |     | NULL    |       |
+------------------+--------------+------+-----+---------+-------+

Following JDBC program inserts records in to this table −

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.Time;
import java.sql.Date;
public class InsertingTime {
   public static void main(String args[])throws Exception {
      //Getting the connection
      String mysqlUrl = "jdbc:mysql://localhost/sampleDB";
      Connection con = DriverManager.getConnection(mysqlUrl, "root", "password");
      System.out.println("Connection established......");
      //Inserting values to a table
      String query = "INSERT INTO Dispatches VALUES (?, ?, ?, ?)";
      PreparedStatement pstmt = con.prepareStatement(query);
      pstmt.setString(1, "KeyBoard"); pstmt.setDate(2, new Date(1567296000000L));
      pstmt.setTime(3, new Time(1567296000000L));
      pstmt.setString(4, "Hyderabad");
      pstmt.execute();
      pstmt.setString(1, "Earphones"); pstmt.setDate(2, new Date(1556668800000L));
      pstmt.setTime(3, new Time(1556668800000L));
      pstmt.setString(4, "Vishakhapatnam");
      pstmt.execute();
      pstmt.setString(1, "Mouse"); pstmt.setDate(2, new Date(1551398399000L));
      pstmt.setTime(3, new Time(1551398399000L));
      pstmt.setString(4, "Vijayawada");
      pstmt.execute();
      System.out.println("Records inserted......");
   }
}

Output

Connection established......
Records inserted......
