Re: find dissimilarity of values comparing two adjacent rows

Maybe. Seems like you need the 'table' with @rownum in it twice (self join). That would lead to two identical (or similar) subqueries, which worries me about concurrency issues.

Sure a stored procedure would be a way to go. And it could use @rownum and/or TEMPORARY TABLE.
