Wenn Sie nur Wochenenden ausschließen möchten, können Sie diese einfach mithilfe einer bedingten Zählung ausschließen, indem Sie Folgendes hinzufügen:
count(distinct case when datepart(weekday, getdate()) <= 5 then date end)
Ihre Abfrage wird also:
set datefirst 1;
select count(distinct(dateadd(d, 0, datediff(d, 0,checktime)))) as workingdays,
count(distinct case when datepart(weekday, getdate()) <= 5
then dateadd(d, 0, datediff(d, 0,checktime))
end) as weekdays
from departments,
dbo.USERINFO INNER JOIN dbo.CHECKINOUT ON
dbo.USERINFO.USERID = dbo.CHECKINOUT.USERID
where userinfo.name='Gokul Gopalakrishnan' and deptname='GEN/SUP-TBL'
and checktime>='2014-05-01' and checktime<='2014-05-30'
JEDOCH Ich würde wirklich empfehlen, einen Kalendertabelle zu Ihrer Datenbank. Es macht alles so einfach, dass Ihre Abfrage folgendermaßen aussehen würde:
SELECT DaysWorked = COUNT(cio.Date),
WeekDaysWorked = COUNT(CASE WHEN c.IsWeekDay = 1 THEN cio.Date END),
WorkingDaysWorked = COUNT(CASE WHEN c.IsWorkingDay = 1 THEN cio.Date END),
TotalDays = COUNT(*),
TotalWeekDays = COUNT(CASE WHEN c.IsWeekDay = 1 THEN 1 END),
TotalWorkingDays = COUNT(CASE WHEN c.IsWorkingDay = 1 THEN 1 END)
FROM dbo.Calender AS c
LEFT JOIN
( SELECT DISTINCT
Date = CAST(CheckTime AS DATE)
FROM dbo.Departments AS d
CROSS JOIN dbo.userInfo AS ui
INNER JOIN dbo.CheckInOut AS cio
ON cio.UserID = ui.UserID
WHERE ui.Name = 'Gokul Gopalakrishnan'
AND d.deptname = 'GEN/SUP-TBL'
) AS cio
ON c.Date = cio.Date
WHERE d.Date >= '2014-05-01'
AND d.Date <= '2014-05-30';
Auf diese Weise können Sie Feiertage, Wochenenden usw. definieren. Es ist so viel flexibler als jede andere Lösung.
BEARBEITEN
Ich glaube, ich habe Ihre ursprünglichen Kriterien falsch verstanden. Dies sollte für Sie ohne Kalendertabelle funktionieren:
SET DATEFIRST 1;
DECLARE @StartDate DATE = '2014-05-01',
@EndDate DATE = '2014-05-30';
DECLARE @Workdays INT =
(DATEDIFF(DAY, @StartDate, @EndDate) + 1)
-(DATEDIFF(WEEK, @StartDate, @EndDate) * 2)
-(CASE WHEN DATEPART(WEEKDAY, @StartDate) = 7 THEN 1 ELSE 0 END)
-(CASE WHEN DATEPART(WEEKDAY, @EndDate) = 6 THEN 1 ELSE 0 END);
SELECT WorkingDays = COUNT(DISTINCT CAST(CheckTime AS DATE)),
BusinessDays = @Workdays
FROM dbo.Departments AS d
CROSS JOIN dbo.userInfo AS ui
INNER JOIN dbo.CheckInOut AS cio
ON cio.UserID = ui.UserID
WHERE ui.Name = 'Gokul Gopalakrishnan'
AND d.deptname = 'GEN/SUP-TBL'
AND cio.CheckTime >= @StartDate
AND cio.CheckTime <= @EndDate;
