I need to show on my index page in one of the collumns data that would

be result of a SQL statment. Is there a universal way to do it? In my

current case I have table A and B, A has many B, B belongs to A. In my

A's index page I need to have data that would be the result of such

SQL statement:

select count(*) from B where A_id=x and B.number > y

The result of this statement is a number and I need to show this

number in one collumn.

Don't use an sql statement, use the ActiveRecord API. Assuming that

you have an A object, an_a, then something like

the_count = an_a.bs.find( :all, :conditions => { :number => x } ).count

should do the trick (untested).
