Hi Frnds,

Can you please help me regarding a stored procedure which calculates monthly attendance for all employees.I am having a attendance table which has following fields:
The start date & end date for a month will be user input.It will check day by day.If any date is absent then it status will be 'A', otherwise status will be 'P'.

Please help me.

you need to use a calendar table for that.
logic will be like below


SELECT c.CalendarDate,
CASE WHEN t.DateColumn IS NULL THEN 'A' ELSE 'P' END
FROM CalendarTable c
LEFT JOIN YourTable t
ON t.DateColumn = c.CalendarDate
WHERE c.CalendarDate > = @StartDate
AND c.CalendarDate < @EndDate + 1
AND DATEDIFF(dd,0,c.CalendarDate)%7 <=4

you need to declare @StartDate and @EndDate as parameters
if you dont already have a calendartable use this instead


SELECT c.CalendarDate,
CASE WHEN t.DateColumn IS NULL THEN 'A' ELSE 'P' END
FROM dbo.CalendarTable(@StartDate,@EndDate,1,0) c
LEFT JOIN YourTable t
ON t.DateColumn = c.[Date]
