After checking the docs, I don't thinks so, but I might have overlooked it. To meet the requirement, I was able write a function for that purpose, based on someone else's code for Oracle.
There is no builtin procedure (function) to compute the number of workdays between two dates... but as you have already alluded to it is easy to write such a function. Example:
create or replace function number_of_workdays( in @date1 date, in @date2 date ) returns int begin if @date1 > @date2 then -- swap dates so that date1 is before date2 begin declare @tdate date; set @tdate = @date1; set @date1 = @date2; set @date2 = @tdate; end; end if; return datediff( day, @date1, @date2 ) + 1 -- total number of days in interval (inclusive) - 2*datediff( week, @date1, @date2 ) -- minus 2*number of sundays (inc d2 but not d1) - ( if datepart( weekday, @date2 ) = 7 then 1 else 0 endif ) -- less 1 if end on Sat. - ( if datepart( weekday, @date1 ) = 1 then 1 else 0 endif ) -- less 1 if start on Sun. ; end;
If you are careful and don't need the date-order check in the above function then it becomes a 'one liner' which will be inlined by the SQL Anywhere execution engine.
