Hi all,
I have a table that lists all inbound calls to a group of ten telephone numbers. We want the table to show a friendly name for each number so it's easier for the user to tell who each call belonged to. For example in the 'to_number' field if the value is +441111111 we want it to display 'Reception'. If the value was +44222222 we would want it to display 'Henry'.
What's the most efficient place to achieve this? e.g. in a transformer, SQL, JSQuery or Mapper?
What would be the best method? Switch Statement, Array comparison etc.?
Thanks in advance,
Jimmy
Hi @farthingcomms, I would suggest two options, and you can use either of these according to your convenience.
- SQL Case statement
- Mapper
I always prefer case statement and, if I am feeling lazier, then Mapper options.

Welcome to the forum @farthingcomms.
Another option would be to use the Lookup Table pattern. Have another table with 2 columns, "friendly_name" and "number". Then use a join on your query to extract the name and use that in your table. Hide the number column in the table properties.
SELECT *, fn.friendly_name
FROM inbound_calls ic
JOIN friendly_names fn ON fn.number=ic.number
If you just have a few phones lines that never change this might be overkill, use the Case or the Mapper. But for 10 numbers I would go with the linked table route. If you get a new phone line, just add a record to the friendly_names table, no code needs to change.
