问题
Microsoft Dynamics NAV uses the datetime of yyyy-12-31 23:59:59.000 to identify yearly closing entries. I am trying to write a report that will bring all of my entries, except for these. The query works fine for 2014 if I explicitly use a WHERE clause of
WHERE [Posting Date] <> '2014-12-31 23:59:59.000')
But I need the query to work for any year. I tried:
WHERE (DATEPART(mm, [Posting Date]) <> 12) AND
(DATEPART(dd, [Posting Date]) <> 31) AND
(DATEPART(hh, [Posting Date]) <> 23) AND
(DATEPART(mi, [Posting Date]) <> 59) AND
(DATEPART(ss, [Posting Date]) <> 59)
But that filtered out everything that was in December or had a day of 31 or an hour of 23, etc...
Is there a simple way to filter a given datetime, but with any year?
回答1:
May be this:
WHERE MONTH([Posting Date]) <> 12 OR
DAY([Posting Date]) <> 31 OR
CAST([Posting Date] AS TIME) <> CAST('23:59:59.000' AS TIME)
Even more short answer:
WHERE YEAR([Posting Date]) <> YEAR(DATEADD(ss, 1, [Posting Date]))

Another thing which you can also do is something like this, which is a slight variation from what you have tried.
WHERE 1 = CASE
WHEN (
DATEPART(MONTH, [POSTING DATE]) = 12
AND DATEPART(DAY, [POSTING DATE]) = 31
AND DATEPART(HOUR, [POSTING DATE]) = 23
AND DATEPART(MINUTE, [POSTING DATE]) = 59
AND DATEPART(SECOND, [POSTING DATE]) = 59
)
THEN 0
ELSE 1
END
In this scenario I just use a CASE to identify those rows which have the date the last second of the year and the evaluation of 1/0 does the rest and filters out the unwanted records.
