I think this is a much better approach.

One thing that stands out in CreateStatistics() is that the check for
a less-than operator can be skipped if there is just a single virtual
generated column, for the same reason as for statistics on a single
expression. I.e., it should be possible to build statistics on a
single virtual generated column of any data type.

Dean
