create table (...) (...) duration interval default 7
do you really think it's worth spending 12 bytes for your intervals? i usually use either timestamps or integers for intervals. btw, as i know default 7 would be 7 msecs :)
hourDay timestamp with time zome
consider using it without a time zone maybe. if you really mean time of a day use time [with time zone]
(...)
if i replace this two data types with varchar2(50) it works but i would like if there's a better choice
it seems oracle still has some probs with sql date/time data types... ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
