Select max int from varchar column

Question

I am trying to retrieve the largest number from a varchar column that includes both numbers and strings. An example of the data I\'m working with:

BoxNumber

Answer 1

Look into casting the column to an int, then selecting the MAX(). I don't know what it will do to columns that contain letters, but it's worth exploring.
