Re: unique values of each column odie_63 Aug 21, 2013 12:38 PM ( in response to Ishan ) Which in-turn means, that COL1 in target table is a mere distinct of COL1 in source table and similarly COL2 in target is DISTINCT of COL2 which again in-turn means that COL1 has absolutely no relation with COL2 in the target table. For numeric replacements all values to be replaced should have unique floating point.
