problem with 2 data bases

[#1]

hi

I have 2 data bases and the problem is that in the first one a couple of rows doubles; but if I load just the first one I don't have any problem

some of columns are keys between them

thanks

Please post an example with source tables, the result you get, and the result you want instead.

hi

I think I solved; I had a couple of syns in table viewer because I have in these 2 bases some common columns

I made a concatenation like here:
