Question

I have such AR code:

@types = Type.find(:all, 
             :conditions => { :TYP_MOD_ID => params[:models],
                              :TYP_PCON_START => params[:year] }, 
             :order => "TYP_HP_FROM")

but how can i do that i see TYP_PCON_START without first 2 symbols and compare?
for example :TYP_PCON_START.to_s[4...6]

Also i need to compare not =, but >= > condition. How to do this?

Answer 1

Use where instead of find. Also i didn’t understand what you mean by how can i do that i see TYP_PCON_START without first 2 symbols and compare?.

@types = Type.where("TYP_MOD_ID = ? AND substring(TYP_PCON_START FROM 4 to 6) >= ?", 
  params[:models], params[:year]).order("TYP_HP_FROM")
