Faster way to delete duplicates -
I have a table where some records have duplicate values in some fields, basically phone numbers (people get a record for each visit to the clients, who supply this data).
I loop through a recordset to delete duplicate records according to a hierarchy of what service they received, and another for duplicate services based on date. That works ok. But there can still be some duplicate records (same hierarchy/date), so I then use
this query to eliminate records based purely on lowest id. This query, though, can take over 5 minutes to run on a few thousand records.
Is there a faster way to do this? Thanks.

Fastest way to delete all rows in MS Access -
I've heard that using TRUNCATE to delete all the rows of a table is faster than using DELETE because TRUNCATE doesn't do logging (but therefore can't be rolled back) while DELETE does do logging (and can be rolled back).
I don't care about rolling back, metadata, or anything like that
