Miguel,
 
I have written sometimes ago on the subject of identifying similar records, and using column contents was one of the possibilities. See IDENTITY.doc on our site in the documents section. The application SKIMALL.mbx is a fair implementation of the document as far as search strategies are concerned.
 
Practically, you have to compare each value with every other one. I think the best way is to create an array of values and do the job in memory. That requires to write (or use) a Mapbasic compiled app.
