在DB2中执行查询时，线程“ main”中的异常java.lang.ArrayIndexOutOfBoundsException

Question

I have the following piece of code: (basically it's a JAVA-DB2 Connectivity test program)

import java.io.IOException;
import java.sql.Connection; 
import java.sql.DriverManager; 
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class TestDB22
{
     public static void main(String  rgs[]) throws IOException, ClassNotFoundException, SQLException 
     { 
        Class.forName("COM.ibm.db2os390.sqlj.jdbc.DB2SQLJDriver");
        Connection  con = DriverManager.getConnection("jdbc:db2:rajdb","db2admin","db2admin"); 
        System. out .println( "From TestDB22, connection obtained " );

        Statement st=con.createStatement();
        ResultSet rs = st.executeQuery( "select * from libids" ); 
        while( rs.next())
        {
            System.out.println(rs . getString(2));

        }

     } 
}

I get the following error:

From TestDB22, connection obtained

Answer 1

I'm tempted to say that there's a bug in the driver. Make sure you're using the latest version.

If that doesn't work, try using a PreparedStatement instead (yes, I know that the query doesn't have any parameters, so please nobody downvote me :)

Statement st = con.prepareStatement("select * from libids");
ResultSet rs = st.executeQuery();

Answer 2

Are you really sure you have the right JDBC Driver.... OS390 os390 is pretty old, and was replaced in 2000 or something. Do you think you should be using the universal type 4 driver: com.ibm.db2.jcc.DB2Driver instead of the os390 specific driver COM.ibm.db2os390.sqlj.jdbc.DB2SQLJDriver ?
