Geting results from DB

Question

I tried to create a method that will connect to a db execute a query and return a ResultSet object
but i get this error
C:\temp>javac connecttodb.java
connecttodb.java:27: cannot resolve symbol
symbol : variable apotelesma
location: class connecttodb
return apotelesma;
^
1 error
This is the code
import java.sql.*;
import java.util.*;
public class connecttodb
public static ResultSet get_info(String databasename, String command)//connect to database databasename and execute a Query command
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); //load up driver
String DataURL=new String("jdbc:odbc:"+_databasename);                //a string with the location of the file
Connection databaseConnection=DriverManager.getConnection(DataURL); //do the connection
Statement statement=databaseConnection.createStatement(); //create a new SQL statement
ResultSet apotelesma = statement.executeQuery(_command); //execute the statement and put the results to apotelesa
databaseConnection.close(); //close the connection
catch(Exception e)
System.out.println(e);
return apotelesma;
What is wrong?

Answer 1

I tried to create a new object that would hold the data when the connection closed but ... I found out that to do what I had in mind (creating a table whose cells I could call at anytime) was actually the easy task of creating my own form of MS Excel. And I would need a hell lot of time to end it ( at least more that I can afford) so ...
I ended up using this code:
import java.sql.*;
import java.util.*;
import javax.sql.*;
public class db_access
public static Connection make_dbconnection(String databasename)  throws SQLException, ClassNotFoundException //connect to database databasename RETURNS A CONNECTION
Connection the_connection;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); //load up driver
String DataURL=new String("jdbc:odbc:"+_databasename);                //a string with the location of the file
the_connection=DriverManager.getConnection(DataURL); //do the connection
return the_connection;
public static void close_dbconnection(Connection databaseConnection) throws SQLException //CLOSES A CONNECTION
databaseConnection.close();
public static ResultSet do_SQL_Query_in_dbconnection(Connection connection, String thecommand) throws SQLException
Statement the_statement=_connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY); //create a new SQL statement Scrollable
ResultSet the_apotelesma = the_statement.executeQuery(the_command); //execute the statement and put the results to apotelesa
return the_apotelesma;
public static void give_SQL_upgrade_command(Connection nati, String _order) throws SQLException
Statement thestatement=nati.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE); //create a new SQL statement
thestatement.executeUpdate(_order); //execute the statement and put the results to apotelesa
I think will help me a lot .. if you have any suggestions please let me know.
