in reply to X, Y Table structure

Just out of curiousity, what use is a transformation such as you show, leaving a table with data that no longer has any link to its IDs?

    If you've seen my reply to ikegami, You can see that I've added IDs in my example.

    FWIW, AFAIK, its temporary, for creating reports, like SQLite::VirtualTable::Pivot shows
    Given this table : Student Subject Grade ------- ------- ----- Joe Reading A Joe Writing B Joe Arithmetic C Mary Reading B- Mary Writing A+ Mary Arithmetic C+ A pivot table created using the columns "Student" and "Subject" and th +e value "Grade" would yield : Student Arithmetic Reading Writing ------- ---------- ------- ---------- Joe C A B Mary C+ B- A+
    Because I forgot all about VIEWS/PIVOT, I did the transformation manually.
