Tom,
So the closest approximation to the default "postgres[ql]" date style
of MM-DD-YYYY (note delimiters) is: SQL,US which returns a
MM/DD/YYYY 00:00:00 value when doing some date arithmetic?
Have I got it right? Egads...in addition to calling substr() to lose
the 00:00:00 (not terribly useful in this context) I'll have to
call perl's binding operator (=~) to swap in hyphens as delimiters.
Bottom line: there is no way to return a MM-DD-YYYY value?
I never realised that the morphology of the traditional Postgres date
was this complex (its declension was not apparent until I used the
INTERVAL keyword) and so I've conditioned my users to using hyphens
as delimiters...argh. Should have used slashes I suppose.
Oh well. Thanks for the help.
