    optimize multiple concatenate

    Federica Barbierato

      Hi all,

      I need to optimize a multiple concatenate.

      The situation is the following:
      Table 1: result of concatenation of 3 identical files with 13 fields.
      I want to concatenate to Table 1, other 3 identical files that have 12 fields each, mostly different from those in the Table 1.

      I tried to concatenate the first 3 identical files, then the other 3 files with each other, and finally the two tables together, but I had to do a re-reading!
      You have a better solution?
