| Hi all,Say I have a table with a field of the letters of the alphabet, which for purposes here I'll say are only A,B,C,D. So my table:ABCDI can create all combinations by SELECT A.letters, B.letters FROM tblAlphabet AS A INNER JOIN tblAlphabet AS B ON A.letters!=B.lettersSoA BA CA DB AB CB DC AC BC DD AD BD CBut what if I want to say that AB==BA, and so return only these unique combinations:A BA CA DB CB DC DCan that be done with a SELECT? |
