Re: How to convert date to integer or vice versa
Stephane, I no longer have access to Design mode as I am retired and have let my 4D Partner license lapse so I’m unable to check out the latest date/number commands. That said, I used to store dates as numbers in a way that sorted the numbers chronologically. I did that by extracting the day, month and year from the date and then combined them into a number by doing something like: Number = 2 digit year x 10,000 + month x 100 + day Incidentally, I think 4D doesn’t actually use integers now - all are longints and I used those to store numeric dates. Hope this helps, Keith There are 3 kinds of mathematician. Those who can count, and those who can't. > On 9/08/2022, at 11:20 AM, Stephane Potvin wrote: > > Hello Keith, > > Thank you for your reply. > > I am indeed old school with 4D.

Re: How to convert date to integer or vice versa
Hi Stephane, Thinking in ”old-school” 4D code, using a trigger can be a good way to enforce a field population rule but an alternative is to create the date field’s object method and populate the integer from there. The code may well be easier to find and maintain from there. If you need help to do the actual conversion (and ‘de-conversion’ if that’s a word) I’m sure you’ll get plenty of suggestions if you ask.

How to convert date to integer or vice versa
I have two fields in a table which must contain the same information. One is date, the other an integer. Rather than entering the same information twice, I would like to enter it in one field and have 4d fill the other field automatically. Can you help with the proper method to do so. Thank you. ** 4D Internet Users Group (4D iNUG) New Forum: https://discuss.4D.com Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **
