I'd like to create an app that accesses db (with 1 table) and outputs its table in a window using FXRuby. Is there any way to make it without using query language like in this example:
require 'pg'
conn = PG.connect(dbname: 'testdb', user: 'postgres')    
rows = conn.exec("select * from users")
And without using Ruby on Rails.
I've also tried to launch this example code, but it doesn't work beacause of the problem with installing sqlite3 gem:
require 'fox16' 
require 'sqlite3.rb' 
include Fox 
class TestApp < FXApp 
   def initialize 
      super('Test', 'Test') 
      @db = SQLite3::Database.new('test.db3') 
      @db || raise("can't connect to database") 
   end 
   def db 
      @db 
   end 
end 
				
                        
It looks like the following should solve your problem (see this reference):
