:blush:

I meant to say

   procedure Patati_Patata is
   begin
      begin
         declare
            S : String := A_Function_Raising_Constraint_Error;
         begin
            --  some code
         end;
      exception
         when Constraint_Error =>
            --  deal with the problem ..
      end;
      --  .. and carry on
   end;
