How to convert a Date value to string in JDBC?
The toString() method of the java.sql.Date class returns the escape format: yyyy-mm-dd of the date represented by the current date object. Using this method you can convert a Date object to a String.
Date date = rs.getDate("Dispatch_Date");
date.toString());Assume we have a table named dispatch_data 3 records as shown below:
+--------------+------------------+---------------+----------------+ | Product_Name | Name_Of_Customer | Dispatch_Date | Location | +--------------+------------------+---------------+----------------+ | KeyBoard | Amith | 1981-12-05 | Hyderabad | | Ear phones | Sumith | 1981-04-22 | Vishakhapatnam | | Mouse | Sudha | 1988-11-05 | Vijayawada | +--------------+------------------+---------------+----------------+
Following JDBC program establishes connection with the database retrieves the contents of the dispatch_data table, converts the date objects into String values using the toString() method and displays the contents of the table along with the Date values (which are converted into String format):
import java.sql.Connection;
import java.sql.Date;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
public class DateToString {
public static void main(String args[])throws Exception {
//Registering the Driver
DriverManager.registerDriver(new com.mysql.jdbc.Driver());
//Getting the connection
String mysqlUrl = "jdbc:mysql://localhost/mydatabase";
Connection con = DriverManager.getConnection(mysqlUrl, "root", "password");
System.out.println("Connection established......");
//Creating a Statement object
Statement stmt = con.createStatement();
//Creating Statement object
stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("select * from dispatch_data");
//Retrieving values
while(rs.next()) {
System.out.println("Product Name: "+rs.getString("Product_Name"));
System.out.println("Name Of The Customer: "+rs.getString("Name_Of_Customer"));
//Retrieving the date
Date date = rs.getDate("Dispatch_Date");
//Converting Date object to String
System.out.println("Date: "+date.toString());
System.out.println();
}
}
}Output
Connection established...... Product Name: KeyBoard Name Of The Customer: Amith Date: 1981-12-05 Product Name: Ear phones Name Of The Customer: Sumith Date: 1981-04-22 Product Name: Mouse Name Of The Customer: Sudha Date: 1988-11-05
