Find duplicates query allows you to search for and identify duplicate records within a table or tables. A duplicate record is a record that refers to the same thing or person as another record.

Not all records containing comparable data are copies. For example, records of two requests that were put on various dates yet that contained indistinguishable things would not be copy records. In like manner, not every copy record contain totally indistinguishable data. For instance, two client records could allude to a similar individual yet incorporate distinctive locations. The record with the obsolete address would be the copy record.

Why is disposing of copy records so essential? Consider the case above. In the event that we had different records for one client, it is hard to see a request history for him on the grounds that the data would be spread over a few unlinked records. We may considerably convey his request to the wrong address if the individual entering the request data chooses an obsolete record. It’s anything but difficult to perceive how having copy records can undermine the trustworthiness and helpfulness of your database.
