I’ve got a left join problem of some sort connecting from linux
FreeTDS/ODBC to SQL Server. It’s similar to the false post I had
earlier, but this is a real problem. Here’s my code:
def find_recipes_for_workorder
@recipe_pages, @recipes = paginate_with_sort :recipes, :per_page
=> 10,
:joins => ‘left join workorder on workorder.workorder_id =
recipe.workorder_id’,
:conditions => [“workorder.name = ?”, params[:workorder][:name]]
render :template => ‘recipe/list’
end
(paginate_with_sort at bottom of email.)
Here’s the top of the error:

Any ideas appreciated.
Thanks,
