For instance can
SELECT foo
FROM bar
WHERE foo BETWEEN 5 AND 10
select 5 and 10 or they are excluded from the range?

between
Yes, but be careful when using between for dates.
BETWEEN '20090101' AND '20090131'
is really interpreted as 12am, or
BETWEEN '20090101 00:00:00' AND '20090131 00:00:00'
so will miss anything that occurred during the day of Jan 31st. In this case, you will have to use:
myDate >= '20090101 00:00:00' AND myDate < '20090201 00:00:00' --CORRECT!
or
BETWEEN '20090101 00:00:00' AND '20090131 23:59:59' --WRONG! (see update!)
UPDATE: It is entirely possible to have records created within that last second of the day, with a datetime as late as 20090101 23:59:59.997
!!
For this reason, the BETWEEN (firstday) AND (lastday 23:59:59)
approach is not recommended.
Use the myDate >= (firstday) AND myDate < (Lastday+1)
approach instead.
If the column data type is datetime then you can do this following to eliminate time from datetime and compare between date range only.
where cast(getdate() as date) between cast(loginTime as date) and cast(logoutTime as date)
Real world example from SQL Server 2008.
Source data:
ID Start
1 2010-04-30 00:00:01.000
2 2010-04-02 00:00:00.000
3 2010-05-01 00:00:00.000
4 2010-07-31 00:00:00.000
Query:
SELECT
*
FROM
tbl
WHERE
Start BETWEEN '2010-04-01 00:00:00' AND '2010-05-01 00:00:00'
Results:
ID Start
1 2010-04-30 00:00:01.000
2 2010-04-02 00:00:00.000
BETWEEN (Transact-SQL)
Specifies a(n) (inclusive) range to test.
test_expression [ NOT ] BETWEEN begin_expression AND end_expression
Arguments
test_expression
Is the expression to test for in the range defined by begin_expression and end_expression. test_expression must be the same data type as both begin_expression and end_expression.
NOT
Specifies that the result of the predicate be negated.
begin_expression
Is any valid expression. begin_expression must be the same data type as both test_expression and end_expression.
end_expression
Is any valid expression. end_expression must be the same data type as both test_expression and begin_expression.
AND
Acts as a placeholder that indicates test_expression should be within the range indicated by begin_expression and end_expression.
Remarks
To specify an exclusive range, use the greater than (>) and less than operators (<). If any input to the BETWEEN or NOT BETWEEN predicate is NULL, the result is UNKNOWN.
Result Value
BETWEEN returns TRUE if the value of test_expression is greater than or equal to the value of begin_expression and less than or equal to the value of end_expression.
NOT BETWEEN returns TRUE if the value of test_expression is less than the value of begin_expression or greater than the value of end_expression.
It does includes boundaries.
declare @startDate date = cast('15-NOV-2016' as date)
declare @endDate date = cast('30-NOV-2016' as date)
create table #test (c1 date)
insert into #test values(cast('15-NOV-2016' as date))
insert into #test values(cast('20-NOV-2016' as date))
insert into #test values(cast('30-NOV-2016' as date))
select * from #test where c1 between @startDate and @endDate
drop table #test
RESULT c1
2016-11-15
2016-11-20
2016-11-30
declare @r1 int = 10
declare @r2 int = 15
create table #test1 (c1 int)
insert into #test1 values(10)
insert into #test1 values(15)
insert into #test1 values(11)
select * from #test1 where c1 between @r1 and @r2
drop table #test1
RESULT c1
10
11
15
I've always used this:
WHERE myDate BETWEEN startDate AND (endDate+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.
