Benchmark, don't ask. Performance questions are very difficult to
answer up front, because there are so many "it depends". What I can
say, is that if you do this in Access, you should do it in a local
Jet database, not not a linked SQL Server table.
If you ask me to place my bets, I put them on Access for this one.
String processing is not SQL Server's best game.
