my query is
SELECT TOP 1000 [action_id]
,DBO.UtcToLocal(creation_date) as Creation_Date
,[event_name]
,[person_num]
FROM [bcore].[dbo].[TEST] WHERE person_num = '00010167'
expected query output:
1684862016-10-22 15:41:22.823CLOCK_IN00010167
1687952016-10-22 19:47:22.823CLOCK_OUT00010167
1688862016-10-23 10:39:22.823CLOCK_IN00010167

Something like this:

SELECT *

FROM

(SELECT 1 as PersonID, '2016-10-21 11:00' as evntTime, 'CLOCK_IN' as evntType

UNION ALL

SELECT 1, '2016-10-21 20:45', 'CLOCK_OUT'

UNION ALL

SELECT 1, '2016-10-22 3:45', 'CLOCK_IN'

UNION ALL

SELECT 1, '2016-10-22 12:45', 'CLOCK_OUT'

UNION ALL

SELECT 2, '2016-10-23 11:00', 'CLOCK_IN') x

WHERE x.evntTime > GETDATE()-1;

You may need to tweak the WHERE clause so it returns exactly what you want.

You may need to tweak the WHERE clause so it returns exactly what you want.

Your answer is perfect if you need to filter for the past 24 hours. As for the original post it looks like the result must match today and yesterday (whole day), so you'll need to filter only on the DATE part. That would lead to altering the WHERE clause to:

...

WHERE x.evntTime > cast(GETDATE()-1 as date)

...
WHERE x.evntTime > cast(GETDATE()-1 as date)

since evntTime seems to be DATETIME datatype, wouldn't that leave an implicit conversion in the execution to compare it to the calculated DATE value? If you want to avoid the conversion, maybe something like:

WHERE x.evntTime > DATEADD(day, DATEDIFF(day, 1, GETDATE()),0)

Your absolutely right 😎

Here's a post with some common date routines. It should be a big help. http://www.sqlservercentral.com/blogs/lynnpettis/2009/03/25/some-common-date-routines/
