So you problem is related to what happens in the inside the 2nd loop with the SQL query? I see two ways forward: (a) reformulate the SQL query so that it only returns unique results (and maybe sums up Column2) or (b) write 2 loops: the first collects the data and keeps a hash/directory/map/set of keys to detect already seen keys and the second. Used in syntax creation. Suppose I want to create a data table (or matrix) that is based of. A data frame.
