Ah, dangit, tamer... 😉 I thought this looked familiar. Why are you double posting? All it's doing is splitting up the answers for this problem. Didn't my answer on my last post on that previous thread do what you want?

For anyone else interested, here's the location of the previous double post.

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Hi Jeff,

Actually, I thought that this case is deferent as we’ve a deferent/modified table structure:ermm: moreover the previous post has been stopped and I didn’t get any other answer for my appendage reply.

Anyway, it’s better because this post is more richer and more interactive, I belive we can ignore the previous one.

And now what do you think regarding my suggestion?

The problem with the (First in/Last out) rule is there may ins with no outs and vice versa for individuals because of the "tailgating" problem. My question is based on that realization... what do you want to report on if that exception occurs?
If it occurs I think we have to report it as "No Out" if we have only In or "No In" if we have only out.

Try

----Sample data

-- timeclock machines log

declare @TIME_LOG table (SNO int, nUserID int, readerid nvarchar(20), dtdatetime Datetime);

insert @TIME_LOG

select 113645, 320417,'in_a', '2014-11-2 8:21:00'

-- for the month

from ufn_Tally2(1,@ndays,1) as d31

left join @Holidays as h

)

select nUserID, [1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[31]

from res

pivot (min(val) for n in ([1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[31]) ) as pvt

It doesn't take your new [readerid] column into account. I agree on what others have said about ensuring you have reliable timeclock machines' output as a first step. But it's rather aministrative problem, plus may be a number of scripts to detect problems and someway to amend raw output.
