If I understand, you want to find any record where there is a number in the field but it doesn't really matter if it's 1 digit or more, and perhaps doesn't really matter what comes before or after the number. If that's not correct, I suggest you clarify what the goal is rather than what doesn't work. I'm wondering if Regex would help. However, I'm not the one to guide you on that but I can say I've seen others post here with regex that provided simple solutions to similar issues that were more complex than what you might be doing. First though, we'd have to make sure we know what the outcome is supposed to be.
The more we hear silence, the more we begin to think about our value in this universe.
