Master calendar with hour

[#1]

Hello,

I need to make a master calendar using a manual startdate and enddate in my load script.

Example:

Using Startdate= 08/01/2013 and Enddate= 12/31/2014

It should generate a table with every year, month, day and hour within the range.

Calendar:

year, month, day, hour

2013, 08, 01, 00

2013, 08, 01, 01

2013, 08, 01, 02

2013, 08, 01, 03

.

.

.

2014, 12, 31, 22

2014, 12, 31, 23

Thank you,

Juan

try like this:

Let vMinDate = Num(Date#('08/01/2013' , 'MM/DD/YYYY');
Let vMaxDate = Num(Date#('12/31/2014', 'MM/DD/YYYY');

MasterTable:

Load

          Year(Date(recno()+$(vMinDate))) as Year,

          Month(Date(recno()+$(vMinDate))) as Month,

          Day(Date(recno()+$(vMinDate))) as Day,

          Hour(Date(recno()+$(vMinDate))) as Hour

Autogenerate vMaxDate - vMinDate;

Hello,

I tried it but all the values in the field hour got a zero.

That is obvious, because when you generate a date it is with 00 hours. if a date is 07-08-2013, then it has no hours component as timestamp, ie. timestamp would be '07-08-2013 00:00:00'( hour, mins seconds all are zero). What do you want the output to be like?

You missed the hour range. Each year, month and date must have an hour range from 00 to 23.

Calendar:

year, month, day, hour

2013, 08, 01, 00

2013, 08, 01, 01

2013, 08, 01, 02

2013, 08, 01, 03

..

2013, 08, 01, 23

2013, 08, 02, 00

2013, 08, 02, 01

..

etc.

Sorry, I should have noticed earlier. Try this:

Let vMinDate = Num(Date#('08/01/2013' , 'MM/DD/YYYY'));
Let vMaxDate = Num(Date#('12/31/2014', 'MM/DD/YYYY'));
Let vLoop=(vMaxDate - vMinDate)*24;

MasterTable:

Load

          Year(Date(recno()+$(vMinDate))) as Year,

          Month(Date(recno()+$(vMinDate))) as Month,

          Day(Date(recno()+$(vMinDate))) as Day,

          Mod(recno(),24) as Hour

Autogenerate vLoop;

Correction:

Let vMinDate = Num(Date#('08/01/2013' , 'MM/DD/YYYY'));
Let vMaxDate = Num(Date#('12/31/2014', 'MM/DD/YYYY'));
Let vLoop=(vMaxDate - vMinDate)*24;
Let vDiff=vMaxDate - vMinDate;

MasterTable:

Load

          Year(Date(mod(recno(),$(vDiff))+$(vMinDate))) as Year,

          Month(Date(Mod(recno(),$(vDiff))+$(vMinDate))) as Month,

          Day(Date(Mod(recno(),$(vDiff))+$(vMinDate))) as Day,

          Mod(recno(),24) as Hour

Autogenerate vLoop;

With that script I am getting this output:

I can see two problems:

1. August 2013 is starting on day 2, it should start on day 1.

2. Each date should have 24 records, one for each hour. For example: Aug 1st 2013 should have 24 lines, one for the hour, starting in 0 and ending in 23.
