Question

update contentpagenav
set active = case
                when active = 0 then active = 1
                when active = 1 then active = 0
         end

I get the following error

Msg 102, Level 15, State 1, Line 3
Incorrect syntax near ‘=’.

No need to re-assign active in your then, the “set active =” is doing that.

   update contentpagenav
       set active =   case
                when active = 0 then 1
                when active = 1 then 0
                    end
