Set Timestamp by using the Prepared Statement
In this JDBC tutorial we will teach how to set the
Timestamp in database table by using the PreparedStatement interface of
java.sql
package. If you want to insert the Timestamp in a table, here you will provide
the setTimestamp method that added date and time in the database table by
using the java.util.Date package. See brief description
below:
Description of program:
In this program we are going to insert the Timestamp
in database table (ray) with the help of PreparedStatement
interface. Working with program, first of we will establish the connection with MySQL
database by using the JDBC driver. When the connection has been
established then we give own query in the prepareStatement method that
returns the PreparedStatement object. After that, we will insert
the data with the PreparedStatement object according to database
table (rname, rtime). Here we wish to add Timestamp in the table
through the setTimestamp method that added the timestamp in a database
table. Finally, we will get the data added in the database table then it will
display a message "row(s) affected" otherwise it shows
"Illegal argument!".
Description of code:
Timestamp(long time);
This is the constructor of java.sql.Timestamp class that takes long
types values to milliseconds. The Timestamp object stored the fractional seconds
but the integral seconds are stored in the underlying date value.
setTimestamp(int index, Timestamp time);
Above method sets the arguments to given java.sql.Timestamp
value. The JDBC driver converts it into the SQL TIMESTAMP
value. It takes integer type index value and Timestamp value in millisecond.
Here is the code of program:
import java.sql.*;
public class SetTimetamp{
public static void main(String[] args) {
System.out.println("Set Timestamp example by using the Prepared Statement!");
Connection con = null;
Timestamp tstamp = new Timestamp(00-00-00);
try{
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection("jdbc:mysql:
//localhost:3306/jdbctutorial","root","root");
try{
String sql = "INSERT ray VALUES(?,?)";
PreparedStatement prest = con.prepareStatement(sql);
prest.setString(1,"x-ray");
prest.setTimestamp(2,tstamp.valueOf("1980-01-14 12:50:45.01"));
int row = prest.executeUpdate();
System.out.println(row + " row(s) affected)");
}
catch (IllegalArgumentException s){
System.out.println("Illegal argument!");
}
}
catch (Exception e){
e.printStackTrace();
}
}
}
