I am trying to find the count of rows on a table.  If I do a
         result=  Table.find_by_sql ("select count(distinct id) ......

It returns an array of Table with Hashes of "select count(distinct id)"
making accessing it a pain
              result[0]['select count(distinct id)']

It seems easier to return all the rows and do a .length on the result
Array.

What is the proper way to do this ?

TIA

There is a Table.count_by_sql class method that you can use.
