I have a rails application where I have to subtract 2 time stamps and display the result on the webpage
I have used the following sql statement and I am getting the results.
select (julianday(resolutions.created_at)-julianday(tickets.created_at))*24 from tickets,resolutions
the value of tickets.created_at is 2010-04-05 18:59:02 which is a time stamp and value of resolutions.created_at is 2010-04-08 08:10:33
Now where do I put this sql so that I can be seen in my webpage.
I tired it in the views page with the following but nothing showed up:
<% @sql = "select (julianday(resolutions.created_at)-julianday(tickets.created_at))*24 from tickets,resolutions" %> <% @t=(ActiveRecord::Base.connection.execute(@sql)) %>
So how do I display it on my webpage?
