Rob, to clarify, your new 'index' column will be based on the value of
the 'part' column and individual column names from the old table?
That is correct.
Perhaps something like this, where [colnum] is derived from column name
like p1? (part+1)*[colnum]
The actual formula I want to use is:
`index` = (30 * part) + [colnum]
The problem is I don't know how to implement this in an SQL statement - what I
want is something like an INSERT...SELECT which can split the SELECTed columns
of a single row (id, c1, c2, c3) into multiple rows in the INSERT: (id, 1, c1),
(id, 2, c2), (id, 3, c3).
Afaik there is no such thing so I need an equivalent method - one that isn't
going to kill my server (like the several attempts I've made so far!)
Run 30 INSERT ... SELECT ...
One for each column.
