Hi, I have a dataset with two phone numbers and I'd like to find records with matching phone numbers regardless if it's the first or the second. For example:
Record# Phone1 Phone2
1 123456789 111111111
2 222222222 123456789
I'd like to say record 1 and 2 is a match
What could you do to find that match? Thanks for any suggestion!
Best,
Hong
