The best approach would be to not allow duplicates in the first place. That is accomplished by having a properly designed (normalized) database structure using foreign key constraints and is ACID compliant.

Based on your question, I assume your database isn't properly designed. Since you haven't given any info about your database, it's impossible for anyone to tell you how to remove your unwanted data.
