Maybe that's because different engines use different syntax. :-)

It's kind of like imperative Haskell - try to avoid it. ;-)

I would first find the duration of each page view, then look for page 
views more than 10 minutes apart.

The duration is the difference between the view time of this row and the 
min of the view time of all rows with a later view time (select by user 
name or whatever your criteria are).  Unobvious. I had to ask that one 
myself.

After that, find the distinct user/duration>=10 pairs.
