I have the follwing statitic and want avoid the Range_ROWS, all should be zero:

RANGE_HI_KEY RANGE_ROWS EQ_ROWS DISTINCT_RANGE_ROWS
2012052802 0 1 0
2012053003 1 1 1
2012053102 0 1 0
2012060102 0 1 0

Because we have a query which used Nested Loops if we have RANGE_ROWS and then the query performes worse.

But we can't change the query at the moment, that is the problem

You can't directly control what gets created in statistics, but you can create specific types of statistics. Try creating a filtered statistic. I'm not sure what you'd filter by in this case, but that can change what is represented within the statistics.

But, as Gail says, for a more specific recommendation, you need to post a lot more information.
