SQL or UNICODE
2 Answer(s)      4 years and 7 months ago
Posted in : SQL


Hi again............

I have got something new that...........

i was using MS Access as the database with my JAVA Japplet....

In my applet i used JTextArea to display the output .....
The output to display is fetched from the database which is connected using DSNless connection as with connection string...

My database contains two columns one with having ASCII and other With UNICODE

1]
when i trying to pass parameter to database i.e UNICODE and fetches ASCII it retrieves nothing to display

2]

when trying to pass parameter ASCII and fetches UNICODE it retrieves only [????] but exactly the same number of chars stored in DATABASE.......

acc. to me their is problem in SENDING and Retrieving the database bcz when trying to fetched ASCII it fetches the exact match and displays......

but with UNICODE nothing ......

I had also change my backhand to SQL SERVER but retrieves same for UNICODE [????] ..............

thanks
waiting for reply

Hi Friend,

In Access database, declare the data type 'Text' to both the fields.
You can use the following code to fetch the UNICODE value.

import java.sql.*;
import java.util.*;
class MSAccess{
public static void main(String[] args) {
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:access");
Scanner input=new Scanner(System.in);
System.out.println("Enter Ascii value: ");
String ascii=input.nextLine();
Statement st=con.createStatement();
ResultSet rs=st.executeQuery("select UNICODE from Data1 where ASCII='"+ascii+"'");
if(rs.next()){
System.out.println(rs.getString("UNICODE"));
}
}
catch(Exception e){}
}
}

Hope that it will be helpful for you.
Thanks
