Hello,
I need to know if I have duplicate records or similar similar in my db. In the past, with SAS, I used a SAS macro for the computation of the dissimilar matrix (for a db with k records, k(k-1)/2 pairs should be examined). There is a way in Oracle to compute the dissimilar matrix or, in general, to detect the similar or duplicate records?
Thanks a lot,
Fabrizio
