In this blog we will know how to insert records in a table
using PreparedStatement of JDBC (Java Database Connectivity) in console window.
Here
we use Type-1 driver (JDBC-ODBC bridge)
Creation of dsn(database source name) for Oracle
Start-Control
panel- Administrative Tools- Data Sources (ODBC)-go to system dsn tab-click add
button-select a driver for which you want to set up data source (for Oracle-
Oracle in XE)-select it and click finish-give any name in data source name
textbox-then click ok button.
Note:
- Here Username=system, Password=pintu and Dsn name=dsn1
Ex:- To insert record into a table by using PreparedStatement
Table Creation
create
table employee(empno int,empname varchar(50),sal int)
/*To
insert record into a table by using PreparedStatement*/
import
java.sql.*;
import
java.util.*;
public
class prepareDemo
{
public
static void main(String args[]) throws Exception
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection
con=DriverManager.getConnection("jdbc:odbc:dsn1","system","pintu");
//step-1
-Reference creation of PreparedStatement
PreparedStatement
pstmt=con.prepareStatement("insert into employee(empno,empname,sal)
values(?,?,?)");
//step
-2 reading from console and providing into sql
Scanner
sc=new Scanner(System.in);
System.out.print("Enter
the Employee Number : ");
int
empno=sc.nextInt();
System.out.print("Enter
the Employee Name : ");
String
empname=sc.next();
System.out.print("Enter
the Employee's salary : ");
int
sal=sc.nextInt();
pstmt.setInt(1,empno);
pstmt.setString(2,empname);
pstmt.setInt(3,sal);
//step-3
pstmt.executeUpdate();
System.out.println("record
inserted");
con.close();
}
}
