How do I filter a string field for anything other than alphabet chars? Case is not important. I'm unsure how to use CONTAINS or perhaps NOT CONTAINS with a list of A-Z, and I don't want to create 26 OR statements in the Filter tool. I'm sure regex can do this in a flash but I'm not sure where to get started.
If my field contains anything other than a-z or A-Z (eg punctuation) then I want to filter it. Thanks
ps - how would I do the above but to allow numbers 0 to 9 as well as letters of the alphabet?
