Hi to all, I write this mail to revamp the discussion about bug 10454 and to have more clear idea about MySQLism, Postgresism and DBIx::xxx As I can see DBIx::xx is the ORM select for support different DB. As I know DBIx::xxx doesn't cover the problem of sequences, so we still need something like Koha::Sequence.pm. I think it is mandatory to use inside it MySQLism, Postgresism, etc. In fact it will became an 'ORM' for sequnces So to improve it I need something that says me if I use MySQL, Postgres, etc. What do you think about use C4::Context->db_scheme2dbi ?
