Обсуждение: interval function question

Howdy:

Running PostgreSQL 7.2.1 on RedHat Linux 7.2

Can someone tell me or point me to where I can
get information on the function 'interval'?  I'm trying
to replicate that to a client's database that's
running Oracle and MS Access and I don't know
what's similar or the definition of that particular
function.

Thanks.

Interval isn't a function in PostgreSQL it's a datatype. In Pg you can
do sensible things like "timestamp - timestamp" to get the difference
between them, that difference is of the type interval.

You might want to read these:

If you have any questions after browsing through those, feel free to
ask.
