If you want to do the same on MS SQL

---- Create function
create function dbo.Julian_date_Conv (@indate int)
returns datetime
as
begin
declare @date datetime
if @indate < 101001
set @date=NULL
else
set @date=dateadd(day, cast(right(@indate,3) as int), cast(cast(left(@indate, 3)+1900 as varchar(4))+'-01-01' as datetime))
return(@date)
end

e.g.
select 105251, dbo.Julian_date_Conv(105251)
