The cold spell certainly was a major inconvenience for me too.

Wasn't that David Fetter? You might be surprised at the broad
applicability of CTEs (recursive CTEs not so much) - I was. They've
sprung up a lot in my production code. I was able to use a recursive
CTE very effectively to populate a graph of historic stock quantities
day-by-day, working backwards from the authoritative current qty in
stock - doing this without recursive CTEs would have been very
difficult. They make complex queries more manageable too.

Pretty good, thanks.

Great. The .ie registrar is *way* too conservative.
