There are two tables, parent and child table.
Foreign key field of the child table is not a required field. If the
data is submitted w/o a value into the foreign key field, what should
I make it as a default value? Should it be "null"?

How can I create such a default value that it depends on the value in
other field (drop down)?
So that the default value would be updated every time I change the value

Please forgive me for using the wrong term here or there. I'm an old Excel 4

I'm sure there is a simple Access 101 answer for this.
I have a subform which the user selects an item description from a combo box

I am designing a new table with a few columns that may or may not have
a value on each row that is inserted.
What issues determine whether to allow a NULL value to be inserted for
that column or define a default value to be used?
I want to think through the repercussions of this decision before I get
into production.

I have a char(11) for SSN, and I would like to default it to
123-45-6789 so I can avoid having nulls in this column, and so I can
easily find the rows in which I need to have a 'correct' SSN
entered/updated.
I tried using just 123-45-6789, and SQL2005 doesn't seem to be
defaulting to this value, it seems to be keeping it as
(((123)-(45))-(6789), and not placing it into this column when a new
row is created....

I have an asp.net/csharp application that requires a particular variable to
work properly. This variable is usually passed via a query string in the URL
when the application is first run but under certain circumstances the query
string may not contain the variable. So I need some way of establishing a
default value if one isn't set.
Is there some way I can set a query string on page_load OR is there some way
I can use a global variable...

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...
