Hello! I am looking for an easy solution for eliminate duplicates but on a row level.
I am having 2 tables. 1 destination for all not duplicated info (a) and 1 for input table (b) which might have duplicates related to table a. Now I am using this kind of insert: INSERT INTO a SELECT fields FROM b WHERE ... NOT EXISTS ( SELECT * FROM a WHERE (a.a,a.b,a.c,a.d)=(b.a,b.b,b.c,b.d) ) Looks like it works but is it any solution for row level compare without naming all fields? For example WHERE (a.*) = (b.*) instead of currently used (a.a,a.b,...)=(b.a,b.b,...).
