i wrote this code to find difference between TotalRequiredHours -
TotalHoursWorked =192 - TotalHoursWorked=186:04 gives result = 5.933334,
, it returns result, Hours are right but minutes part seems to be incorrect. e.g. why ? how to find exact minutes part like int his format 5:56
CODE:
ALTER FUNCTION [dbo].[GetHoursDeducted]
(
@emplID int,
@month varchar(50)
)
RETURNS float
AS
BEGIN
Declare @StartDate Date, @EndDate Date, @mydate date,
@TotalDays int, @TotalHours int, @BasicSalary float,
@BSalaryHour int, @TotalSalary float, @hms varchar(100),
@hrs int, @mts int, @TotalHoursWorked float,
@hrsDeducted float
set @hms = (Select OverallTime from MonthlyRecord where EmplID = @emplID AND Month = @month )
Set @hrs = LEFT(@hms,charindex(':',@hms)-1)
set @mts=RIGHT(@hms,len(@hms)-charindex(':',@hms))
set @TotalHoursWorked = @hrs + (@mts/60.0)
Set @mydate = GETUTCDATE()
Set @StartDate = (SELECT CONVERT(VARCHAR(25),DATEADD(dd,-(DAY(@mydate)-1),@mydate),101))
Set @EndDate = (SELECT CONVERT(VARCHAR(25),DATEADD(dd,-(DAY(DATEADD(mm,1,@mydate))),DATEADD(mm,1,@mydate)),101))
Set @TotalDays =((DATEDIFF(dd, @StartDate, @EndDate) + 1)
-(DATEDIFF(wk, @StartDate, @EndDate) * 1)
-(CASE WHEN DATENAME(dw, @StartDate) = 'Sunday' THEN 1 ELSE 0 END))
Set @TotalHours = (@TotalDays * 8)
Set @BasicSalary = (Select BasicSalary from HrEmployee where EmplID=@emplID)
--Set @TotalHoursWorked = (Select OverallTime from MonthlyRecord where EmplID = @emplID AND Month = @month )
Set @BSalaryHour = @BasicSalary / @TotalHours
Set @TotalSalary = @BSalaryHour * @TotalHoursWorked
Set @hrsDeducted = @TotalHours - @TotalHoursWorked
--------------------------------------------------------------------------------------
-- Return the result of the function
RETURN @hrsDeducted
END
