Does MS SQL Server's “between” include the range boundaries?

Question

For instance can

SELECT foo
FROM bar
WHERE foo BETWEEN 5 AND 10

select 5 and 10 or they are excluded from the range?

Answer 1

if you hit this, and don't really want to try and handle adding a day in code, then let the DB do it..

myDate >= '20090101 00:00:00' AND myDate < DATEADD(day,1,'20090101 00:00:00')

If you do include the time portion: make sure it references midnight. Otherwise you can simply omit the time:

myDate >= '20090101' AND myDate < DATEADD(day,1,'20090101')

and not worry about it.
