I have a table in this instance titled industryimport. It is formed by using a merge statement and combining 8 other tables into one. I have failed to find a way to de-duplicate using union of the 8. So once industryimport is formed, is there a way to de-duplicate based on all 22 columns/fields being identical. There is a compound primary key composed of 9 fields and 13 foreign keys, if that is of any relevance. Just Just looking for some basic conceptual to get started.
