Find duplicates in a table "Users" where you must analyze certain fields like "first_name", "last_name", "address", "email" to conclude if they are indeed valid duplicates (obviously, the unique field "user_identification_number" has different values, hence the need to find and identify duplicate accounts)
The only criteria that is s MUST (where clause) is that at least one of the duplicate record/s must have a value of 0 in the field "criteria".
Examples: "email" in a record is identical to "email" in another record is a guaranteed duplicate.
"FirstName" in a record in a record is identical to "FirstName" in another record is NOT a guaranteed duplicate (for this the "LastName" must also be identical).
Bottom line: there is no sure fire way to query for accurate duplicates- I just want a generic guidance so that I can eyeball and identify the duplicates myself after setting some basic criteria.
