Is it possible to put the results from a query in a variable to use in the bean class?

Question

Hello, I'm using JDeveloper 12.1.2.0.0
I would like to keep the result of my queries (the method i created in the AppModule) in a RichTable or other type of variable so i can have the results stored and i don't have to do unnecessary queries after. I don't think the query is the problem but keeping the results.
I've tried to do that by using this:
    public String testVFactSales(String conditions) {
        PreparedStatement query = getDBTransaction().createPreparedStatement("" + "select * from v_fact_sales " + conditions, 0);
        //ResultSet rs;
        ResultSet result;
        //RichTable result;
        //String result = null;
        try {
            //query.setString(1, conditions);
            // query.execute();
            query.execute();
            result = query.getGeneratedKeys();
            query.close();
            System.out.println("Result: " + result.toString());
            return result.toString();
        } catch (SQLException e) {
            e.printStackTrace();
        return "";
As you can see, i've already tried some solutions but so far i only get errors (cannot convert or null exception, when i try to put the result in a richtable in my bean class)
Any ideas?
This is very important for me, since it would improve the performance of my project a lot.

Hey Arunkumar,
I came to this conclusion since i'm using binding variables with my where clauses.
I've measured the time and i get really bad time responses.
This is my main table query, where all the others selections will be filter the search in this table:
SELECT VFactSalesNew.N_SALES,                              
       VFactSalesNew.QUANTITY,                              
       VFactSalesNew.PRICE,                               ,                              
       VFactSalesNew.FK_STORE,                              
       VFactSalesNew.ID_ANO,                              
       VFactSalesNew.QUARTER   
FROM V_FACT_SALES_NEW VFactSalesNew                              
WHERE                                          
((nvl(:var_dimCoin,'0') ='0' OR FK_COIN IN (select * from THE(select cast( in_list(:var_dimCoin) as mytableType ) from dual ) a) )                                                   
AND                                                 
(nvl(:var_dimProduct,'0') ='0' OR FK_PRODUCT IN (select * from THE(select cast( in_list(:var_dimProduct) as mytableType ) from dual ) a) )                                                  
AND                                                 
(nvl(:var_dimCustomer,'0') ='0' OR FK_CUSTOMER IN (select * from THE(select cast( in_list(:var_dimCustomer) as mytableType ) from dual ) a) )                                                 
AND                                                 
(nvl(:var_dimStore,'0') ='0' OR FK_STORE IN (select * from THE(select cast( in_list(:var_dimStore) as mytableType ) from dual ) a) )                                                
AND                                                 
(nvl(:var_dimSeller,'0') ='0' OR FK_SELLER IN (select * from THE(select cast( in_list(:var_dimSeller) as mytableType ) from dual ) a) )                                                  
AND                                                 
(nvl(:var_dimProject,'0') ='0' OR FK_PROJECT IN (select * from THE(select cast( in_list(:var_dimProject) as mytableType ) from dual ) a) )                                                  
AND                                                 
(nvl(:var_ano, '0') ='0' OR ID_ANO IN (select * from THE(select cast( in_list(:var_ano) as mytableType ) from dual ) a) )                                                  
AND                                                 
(nvl(:var_treemap,'0') ='0' OR PK_REGION IN (select * from THE(select cast( in_list(:var_treemap) as mytableType ) from dual ) a) )
