Subj:   Re: add_months for integer-type dates
 
From:   Geoffrey Rommel

  We're often dealing with monthly data. That's why our DWH architect decided to define dates as integer of the format YYYYMM.  


If you're planning to write a UDF, you can easily split the integer into year (date_code / 100) and month (date_code % 100) portions. Then you can compute a sequential month number (e.g. Jan of year 0 = 1, Jan. 2000 = 24001, etc.), add or subtract as needed, and convert it back to the coded form.

Come to think of it, using a sequential month number would probably have been a better choice to begin with, but it's probably too late to change that now.
