Removing duplicates from a SQL database is always a fun exercise...

I had the dubious pleasure last year, when I discovered that a table on the production system didn't have a unique index on one of the keys, which led to duplicates there, and ultimately, because this was a mapping table for userId values between two systems, to generating duplicate user records.
