Re: histograms, buckets, and bind variables

During an Hard Parse the Histogram does make a difference but it should not after that if you are using Bind variables ...

So if you see a diffeent plan everytime it is Hard Parsed with different values then yes that is valid. If you set an Event and Run a Query i think it is always hard parsed.
