Great video Erik. The dreaded 'put everything into large varchar fields' antipattern rarely mentions the memory issue even though it can have pretty dire consequences as you prove. QQ for you though .... how much memory would be allocated to a varchar(max) and nvarchar(max) field? Also, which is the best field in the Actual Execution Plan to ascertain how much memory was actually needed for the data (ie. to see how much the plan actually wasted)?
