I have a user assigned multiple roles and a role can be inherited from
multiple parents (see below). How do I answer such questions as "How
many roles does the user belongs to?"
I answered the above questions by using .NET but I think it can be
more efficient by using just SQL. I would appreciate if you can give
me an answer.
Thank you.

Is there a way to store an indefinite number of keys in one field and
self join them? Imagine, for example, you have a table of users with a
"friends" column. Say user 1 is friends with users 9, 7, 24 and 6; then
would it be possible to store this
array/list/whatever-you-want-to-call-it into user 1's friends cell and
extract the join in a query, some how? An easy and obvious way, that
is; I can think of string processing hacks ;)
Thanks...

HI--I have 2 tables
Cut: cut ID, HistNumb, Block, date: Cut Id is the primary key, the other 3 fileds are indexed to be
unique
Slides: Cutid SlideID, and various other fields: there can be multiple slide records per CutID.
This table is a subdatashet of the Cut table--so the CutId is stored in it
I have a form based on a query between the 2 tables for adding slide records

Hello,
I have a multithreaded windows NT service application (vb.net 2003) that I
am working on (my first one), which reads a message queue and creates
multiple threads to perform the processing for long running reports. When
the processing is complete it uses crystal reports to load a template file,
populate it, and then export it to a PDF.
It works fine so far....

I'm really not sure how to go about this in Access. What I've created
is a table for each location. Those tables are identical in format but
different in information.
The tables are named after key points such as the store number and the
store ID. The fields of those tables are generic fields such as sales
per day, bank deposit and what not. The first field for each store
table is the date and I've set that as the primary key as one...

I've searched google intensely on this topic and it seems noone really knows how to approch this.
The goal I don't want clients to give out their usernames and passwords to friends, since the site
relies on subscrption fees.
Sessions ID's are matched between the browser and the server. So a users can login with same
username and password and those sessions are tracked individually.
Some suggest create table fields with the session ID...

On my form I have combo boxes. These combo boxes, after updating
them, populate respective listboxes that are located below the combo
boxes on the same form. I am trying to use a "generate report" button
located on my form to print all of the list box values (that have been
updated via selection from combo boxes) from the form to the report.
I've tried using a macro with the code:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
