Anything you want...

IBM i specific articles from Gene Cobb can be found regarding their use in
Web Query.
https://www.mcpressonline.com/analytics-cognitive/db2/tech-tip-converting-legacy-date-fields-to-db2-web-query-dates-part-ii

The above is based on the info in this Redbook (starting at p, 85)
https://www.redbooks.ibm.com/redbooks/pdfs/sg248379.pdf

But a google search for SQL Calendar Table or SQL date dimension will turn
up lots of others.

For the conversion part, you simply want the dates stored in multiple ways

- date
- numeric
- char

whatever is useful to you.

You then include any other fields that are useful to you and your reporting
needs..

- Fiscal year
- Fiscal quarter
- Day of the week (Monday, Tuesday, etc.)
- Month of the year (January, February, etc.)
- Season (spring, summer, autumn, winter)
- Super Bowl Sunday flag (Y or N)
- Day before a holiday flag (Y or N)
- Day after a holiday flag (Y or N)
- Full moon flag (Y or N)
- And so on

Some very interesting replies!

What is in the date table exactly?

Is there also anything simple to get back to numeric YYYYMMDD from the
date? At present I'm doing something like :
myDate = year(dateCol) * 10000 + month(dateCol) * 100 + day(dateCol)

Hello,

I came up with this in order to convert a 8,0 numeric field to a date
that
seems to work. Format is YYYYMMDD so it would be a bit different for most
of you.
Can anyone suggest something to make it easier on the eye? Thanks!

select

date('0001-01-01') +
(int(myDate/10000) - 1) years +
(int(mod(myDate , 10000)/100) - 1) months +
(mod(mod(myDate , 10000), 100) - 1) days
from myFile
