Yes, a Java Program works, it does show a certificate error, but, it does at least yield results

Here is the Java Program that partially works

package db;

 

 

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;

 

public class jdbcTeradataConnectionTestCertificate {

 

 

 

    public static void main(String[] args) throws Exception 
    {

try 
{

String serverURL = "jdbc:teradata://172.28.130.20/LOGMECH=LDAP"; // Wo
+rked on my laptop, but not main main pc
Class.forName("com.teradata.jdbc.TeraDriver");
String username = "!NEDVFCollections";
String password = "xxxxx";

Connection con = DriverManager.getConnection(serverURL, username, pass
+word);

String query="select top 2* from NED_COLL_TABLES.T_PM_PREPAY_FIN WHERE
+ SYS = 8773";
        
        PreparedStatement stmt=con.prepareStatement(query);
        ResultSet rs=stmt.executeQuery();
        while(rs.next()) 
        {
            String col1=rs.getString(1);
            System.out.println("col1="+col1);
        }

}

 

 

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

 

 

}

Here are the results it yielded, as one can see, it did print out values "GBR"
