TSQL Challenge 54 - Find the longest matching area code from phone numbers
An IVR application stores call information into a SQL Server table. A reporting application needs to read phone numbers from the call log and identify the country-code/area-code that is part of the phone number. Your job is to write a query that identifies the longest matching country/area code from each phone number based on the information stored in an area-code reference table.
