Table creation with records

create table employee(empno int,empname varchar(50),sal int)
insert into employee values(1,'raj',10000)
insert into employee values(2,'raju',20000)
insert into employee values(3,'rajesh',30000)

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.

public static void main(String args[]) throws Exception
Connection con=DriverManager.getConnection("jdbc:odbc:dsn1","system","pintu");
Statement stmt=con.createStatement(1004,1008);
Scanner sc=new Scanner(System.in);
System.out.print("Provide employee no :");
int no=sc.nextInt();
ResultSet rs=stmt.executeQuery("select * from employee where empno="+no);
