Hello.

How would I get last 12 digits of a string using mysql?

Let's say I have a varchar field with a tracking number, that may be anywhere from 5 to 20 varchars long. But I only need to select last 12 digits or less if there are less.

so in a field = 12345678123456789012

I would only need to get what's in brackets

field = 12345678[123456789012]

I saw a few examples using mid, etc, but they dont' produce the desired result or I can't find an example that makes sense :-(

Thank you.
