If you added a unique index, then inserts or updates that succeeded on A and B could fail on C. Other than that, it seems like it should work, but it would complicate recovering from replication problems. But what would be the benefit of doing it rather than adding the indexes to all copies of the tables? > Is there a command/query I can issue to show me the indexed columns > for tables in DB-C (I inherited these DB's so there's still a lot I > don't know about their structure).
