I have a table(e.g. tableA) like this:
| Name | Startdate | Enddate | |---------------------------------| | a | 2012-07-01 | 2013-06-30 | | b | 2011-05-01 | 2012-04-30 | | c | 2010-01-01 | 2013-12-31 | | d | 2013-01-01 | 2014-12-31 | | e | 2011-07-01 | 2012-06-30 |
I want to get a name from the table who is active between 2012-05-01
and 2012-10-31
. From above table the result should be a,c and e.
What I have done is as following:
SELECT Name FROM tableA WHERE startdate<='2012-05-01' AND enddate>='2012-10-31'
But I am not getting the correct result.
Solução
declare @T table
(
Name char(1),
Startdate datetime,
Enddate datetime
)
insert into @T values
('a', '20120701', '20130630'),
('b', '20110501', '20120430'),
('c', '20100101', '20131231'),
('d', '20130101', '20141231'),
('e', '20110701', '20120630')
declare @StartDate datetime = '20120501'
declare @EndDate datetime = '20121031'
select Name
from @T
where Startdate < @EndDate and
Enddate > @StartDate

Placement of comparison operator were creating problem check this
SELECT Name FROM tableA WHERE startdate>='2012-05-01' AND enddate<='2012-10-31'
If you are wanting to find any results that occurred during the period then utilize BETWEEN:
SELECT Name FROM tableA WHERE startdate BETWEEN '2012-05-01' and '2012-10-31'
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.
