really? i was thinking really hard on how to do it in sql, but didn't found
any way to achieve it. actually - i dont really think it would be possible
at all in standard sql. but then - maybe i'm wrong.
Well, it looks to me like the main problem is you're trying to convert a
table like: (advert_id, cust1, cust2, cust3) to: (advert_id, codename,
codevalue).
If you do that separately at the start of the process, (one query per
custom column in the old table) then it becomes straightforward.
