John,
Sure you can - you make a method to extract the data you want. In selection
based listboxes you can put the method in a column formula.
It's definitely easier in v17 but I've been using this in v15 for a long
time.

As always sql does not see object fields. So if you use sql to move data
around.

Just note that you won't be able to see any of the data in an object field if
you are displaying records in a list box. Some possible options now in version
17 if you are using collections/entity selections.

Kirk,
since I don't have objects yet...
Trigger actions - 1 method
tracking actions (including created and modified) - 4 methods

Wow, you guys are the best—GREAT idea! I think we all need to use objects more
often and this is a great example—thanks Kirk.

Robert,
My thoughts on the created by/modified by stuff:
1) I moved all this to a single object field. I call it '_meta' and it's on
every table I want to manage.
2) At a minimum the field has:
{"created"; {"name: "", "date": ""},
"modified"; {"name": "", "date": ""}}
3) I wrote a few (I thin
I use 2 fields (nearly) every table, some linking (many to many) tables
do not have this.
[Table]Created_Who [text]
[Table]Modifed_Who [text]
both fields track the same info Current User, Date, time (in that
order and that format)
This info is updated, most often by a trigger, using the Databa
Hi Chuck, I think in this case, this makes sense. I never thought about
tracking all record updates or going further… all updates on chosen fields. I
recall in the past that other developers that cared about such things had a 3-4
fields added to each record and could easily see who created and w
I think the strategy depends upon need. If all you need to to know
who created, data and time created and last modified by, last modified date
and time, then I would add fields to table in question.
If you have a need to track who made every modification, I would put that
in a sperate table. You c
At a minimum, I just have the simple need of recording “CreatedBy” and
“ModifiedBy” values (username or ID) for one particular table. I do have extra
fields already in that table that could be repurposed and I would probably add
“DateModified” to that. However, that’s three fields used just for
12 matches
