I want viewers to compare state laws on a single subject.
Imagine a three-column table with a drop-down box on the top. A viewer
selects a state from the list, and that state's text fills the column below.
The viewer can select states from the drop down lists above the other two
columns as well. If the viewer selects only one, only one column fills. If
the viewer selects two states, two columns fill. Etc.
I could, if appropriate, have...

Hello,
I'm just returning to MS SQL Server after two years of dealing with
Sybase ASE. I need to drop a column, using the alter table command.
I keep getting an error indicating that a constraint is using the
column. Here is the create script for the table
create table mytable
(col1 char(1) not null,
col2 char(1) default 'A' not null
)

Is it possible to link one drop-down box to another? For example, if a
name is chosen from a drop-down list, can another drop-down list then
automatically display the person's office as a result of the choice
made in the first drop-down list? If so, how can that be done? I am
working with 'Teach Yourself Microsoft Access' and I didn't see it
discussed in that book (if it's even possible to do). Or would I just
have to create linked tables...

Hello!
I have a Problem.
A table with a ForeignKeyRef exits. The Name of the field with this FK-Constraint is 'id_employee'
because it is referencing the field 'id_employee' in 'public.sd_employee'. I drop this column of the
table with cascade in a script:
ALTER TABLE public.sd_messaging_participant DROP COLUMN id_employee CASCADE;

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

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
