Well I'm not much better!

Just about sorted crosstab (at least conceptually) and made an awkward 
discovery in the process.

CREATE TABLE `Answer` AS SELECT ... seems innocuous enough.

But I hadn't noticed before that it brings NULL/NOTNULL settings from 
SELECT columns into the new table. The benefits are obvious, but is 
different to pdox which generates the Answer table unkeyed. Ho Hum :(
