Question

I have the following fields in a SQL Database:

@EstimatedRequiredTimeHours DECIMAL(18,2) = NULL, 
@ScheduledStartDate SMALLDATETIME = NULL,
@ScheduledEndDate  SMALLDATETIME = NULL

I need to calculate the @ScheduledEndDate by adding the @EstimatedRequiredTimeHours to the @ScheduledStartDate.

I’m not entirely sure how to do this, DATEADD() doesn’t seem like exactly what I want and my SQL isn’t too up-to-date.

Any help would be appreciated.

Thanks.

Answer 1

Dateadd accept integers as second parameter, so fractions are truncated, in order to include them, just multiply with 60*60 and add seconds instead.

set @ScheduledEndDate = dateadd(ss, @EstimatedRequiredTimeHours * 3600, @ScheduledStartDate)
