The database WORKCALENDAR has records only for working days.
I want to declare a variable that is '1' in case that the query that checks if today is a workingday returns a match or '0' in case it doesn't.

declare @workday binary
set @workday = ..??... from dbo.WORKCALENDAR where DATEDIFF(day, TRANSDATE, GETDATE()) =0

I've been trying with ISNULL in the last hour but I just don't get it.
What function does this trick?

declare @workday int = 0
select @workday = 1 from dbo.WORKCALENDAR where DATEDIFF(day, TRANSDATE, GETDATE()) =0

==========================================
Cursors are useful if you don't know sql.
SSIS can be used in a similar way.

declare @workday int
set @workday = 0

if exists(select * from dbo.Workcalendar where DATEDIFF(day, TRANSDATE, GETDATE()) =0)
begin
set @workday = 1
end

No, you're never too old to Yak'n'Roll if you're too young to die.
