The other day I had to setup a new data warehouse that will be used for reporting with MicroStrategy. Part of it was setting up the date dimension including the transformation tables. I had a quick look online and couldn't find any script doing the work for me so I created them myself (with the help of a colleague). All you need is an existing date dimension with date_id, year_id, quarter_id, month_id and week_id, you can find plenty of scripts for that online. YTD table select t1.day_id, t2.day_id INTO YTD_DAY from LU_DAY t1, LU_DAY t2 where t1.day_id >= t2.day_id and t1.year_id = t2.year_id QTD table select t1.day_id, t2.day_id as qtd_day_id INTO QTD_DAY from LU_DAY t1, LU_DAY t2 where t1.day_id >= t2.day_id and t1.QUARTER_id = t2.QUARTER_id MTD table select t1.day_id, t2.day_id as mtd_day_id INTO MTD_DAY from LU_DAY t1, LU_DAY t2 where t1.day_id >= t2.day_id and t1.month_id = t2.month_id WTD table select t1.day_id, t2.day_id as wtd_day_id INTO WTD_D
