Partial Phone Number Match

[jbowley]

I have 2 databases that have a relationship on phone numbers

On database 1 I want a field that will look at database 2 to see if that phone number is there.

But I am not looking for exact match. I am looking for area code - prefix match.

Example database one has 222-333-4000

I want to do partial match on just first 7 characters.

So if database 2 has 222-333-4125 & 222-333-4287

then it would show there is a match

I tried a calculation field

If(Left(Phone;7) = Left(TBN_ADM_IC_231::Phone;7);"XX";"")

also tried

PatternCount (Left(TBN_ADM_IC_231::Phone;7) ; Left(Phone;7))

But they only returned exact matches.

there's an obvious solution that should work - and that is to have a calculation (in both) that says:

Phone_first7:(left(phone;7)) - or whatever you want to do to strip out any non numberic characters - and then either use this as the match field or at least compare these two.

Try this. Assuming Contacts2 is the number you want to check against contacts.

I read this wrong, sorry.

I must be missing something.

Database 1 calculation field Phone7=LEFT(Phone;7)

Database 2 calculation field Phone7=LEFT(Phone;7)

They both display 222-333

Yet when I create a comapre field

ComparePhone=If(Database2::Phone7=Phone7;"DJM";"")

still not working right.

I think that you are trying to use a relationship correct?

If you are matching on DB1::Phone7 to DB2::Phone7, then all you have to do is Case ( IsValid ( DB2::Phone7); "DJM") or you can also use Case ( not IsEmpty ( DB2::Phone7); "DJM").

Tried this & I can still only get it to work if exact match? Any suggestions. If you were going to do this please walk me through each step you would take. Thanks
