How to place two constraints on a single column

Question

hii
i have a column which will store data in date format
now i need all the records whose value is not null in tht column and date should be from last week to current week
is there any other way to write query other than like this
let us assume its terminate date coloumn
select * from <tablename>
where terminate date is not null
and terminate date between sysdate+7 and sysdate-7
or
select * from <tablename>
where terminatedate between sysdate-7 and sysdate+7
and terminatedate not null

Answer 1

Err... ok I may have said that wrong...
But I still think it might be exclusive, no?
eg. you store 1, 2, 3, 4 and 5 in a table.
select *
from table
where number between 1 and 5
and you will get 1, 2, 3, 4
That is exclusive of the second value.
That is the standard definition of exclusive.
Inclusive includes the last value (eg. 5).
Exclusive does not.
There is the exception of the time, which I would like to know more about.
I don't mean to ruffle everyone's feathers though!
Sorry if I sound like a know-it-all :P
I freely admit that I don't!!
So back onto the time thing...
Say if I store...
01/01/07 00:50:00
01/01/07 18:20:00
02/01/07 05:35:00
02/01/07 20:20:00
03/01/07 00:00:05
03/01/07 23:50:00
in a table
and i go
select *
from table
where date between to_date('01/01/07','dd/mm/yy') and to_date('03/01/07','dd/mm/yy')
Won't I get
01/01/07 00:50:00
01/01/07 18:20:00
02/01/07 05:35:00
02/01/07 20:20:00
back?
and if i go
select *
from table
where date between to_date('01/01/07','dd/mm/yy') and to_date('04/01/07','dd/mm/yy')
OR
select *
from table
where date between to_date('01/01/07','dd/mm/yy') and to_date('03/01/07 23:59:59','dd/mm/yy HH24:MI:SS')
I'll get them all?
