In this Code Snippets we will know how to find the related records from the table when we enter one field value in console.

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

Table Creation with values

create table emp(empno int,empname varchar(50),sal int,job varchar(50))
insert into emp values(1,'Raj',10000,'Manager')
insert into emp values(2,'Ravi',20000,'Director')
insert into emp values(3,'Rahul',30000,'Producer')

SearchRecords.java

import java.sql.*;
import java.util.*;
public class SearchRecords
{
public static void main(String args[]) throws Exception
{
int eno,esal;
String ename,job;
char ch='c';
Scanner sc=new Scanner(System.in);
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection("jdbc:odbc:dsn1","system","pintu");
ResultSet rs;
Statement stmt=con.createStatement();
do
{
System.out.print("\nEnter the Employee Number : ");
eno=sc.nextInt();
rs=stmt.executeQuery("select * from emp where empno like "+eno);
rs.next();
ename=rs.getString("empname");
job=rs.getString("job");
System.out.println("\nNAME: "+ename+" ENO: "+eno+" Job: "+job);
System.out.println("\nPress any key to quit or c to continue :");
ch=(char)System.in.read();
}
while(ch=='c' || ch=='C');
con.close();
}
}
