Introduction
In this blog, we will know how to find the related records
from the table when we enter one field value in the 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 a data source (for Oracle-
Oracle in XE)-select it and click finish-give any name in the data source name
textbox-then click ok button.
Note:
- Here Username=system, Password=pintu and Dsn name= dsn1
Table Creation with valuesb
- 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();
- }
- }
