Answer / shanu zabeen

import java.sql.*;
import java.io.*;
public class Employeedetails
{
public static void main(String args[])
{
try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection
con=DriverManager.getConnection("jdbc:odbc:employeeds");
Statement st=con.createStatement();
ResuleSet rs=st.executeQuery("select * from emp");//this
executes the query and get all the details from the table
employeeds
System.out.println("EId Ename Salary\n");
while(rs.next())
{
System.out.println(+rs.getInt(1)+"
"+rs.getString(2)+" "+rs.getString(3));

}//here 1 2 3 mentioned are the indices which are unique and
instead of 1 2 3 u can also provide the name of that
particular column name
and getXXX(index) ,here xxx is the type of the column like
int or float or string
st.close();
con.close();
}
catch(Exception e)
{
e.printStackTrace();
}

}
}

import java.sql.*;
import java.io.*;

public class JDBCConnection
{

public static void main(String args[])
{
Connection conn;
Statement stmt;
ResultSet rs;

try
{
//loads JDBC driver
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
}
catch(Exception e)
{
e.printStackTrace();
}

try
{
//set connection string

conn=DriverManager.getConnection("jdbc:odbc:employeedsn");//here
loads dsn named empdsn

//creates statement
stmt=conn.createStatement();

//to get records from database using
resultset
rs=stmt.executeQuery("select * from emp");//for dis 1st
create emp named table
System.out.println("EId
Ename DOB Dept
Salary\n");
while(rs.next())//moves cursor to the next record until
it reaches d last record
{

System.out.println(+rs.getInt(1)+"
"+rs.getString(2)+" "+rs.getString(3)+"
"+rs.getString(4)+" "+rs.getInt(5));

}
stmt.close();
conn.close();
}

catch(Exception e)
{
e.printStackTrace();
}
}
}

Note:
-create emp table 1st wid attributes eid,ename,dob,dept,n
salary
-to add dsn(data source name)go to control
panel->Administrative Tools->Data Sources (ODBC) then one
small window will get opend..
-click on System DSN tab->Add->n select "Microsoft Access
Drive(*.mdb)"->finish->type Data Source Name(as i hv typed
in program "employeedsn" if u dnt want to change that dsn
which is written in d line
conn=DriverManager.getConnection("jdbc:odbc:employeedsn")

-you can give ne name tht u want instead of employeedsn...u
only need to provide d same name in Data Source Name

-next is no need to provide nethng for description
-then click on->select(to select database in *.mdb form)
---to select database table select drive on which u hv
saved ur database table n select that table by going to d
folder where u hv stored it by going to an appropriate directory
----if u select correct directory,table name will b
displyed in left hand side list box which then u need to
select n click on "OK" n again click on "OK"
----Your DSN will be displyed in System Data Sources List
---click on Ok n once you done this run the program
