Hi,
This question has been bothering me for some time. A lot of people
seem to "think" XML is the king of data problems, and I've heard that
next version of SQL Server is going to have a strong XML flavor,
meantime, I seem to get the impression that a large number of
hard-core relational model gurus do not seem to be that impressed with
XML (technical value of this extra layer seems to be limited while
business value might be...

I'm looking for documentation and would not turn my nose up to
any code from anybody who thinks they are good at the design

A Yahoo-like drill-down menu that is a series of categories and nested
categories is a hierarchical relational data model. An example can

Hello,
I need to take a set of input tables and create an XML output file. The
format of the XML output must be user-definable and must be intuitive
enough for non-techies to use.
input table(s) + SomeSchemaDefinition ==XML file

currently 18 tables. When I change the Database Diagram for my
database I save the copy the list of changed tables to a notepad text
file; then one at a time I delete the changed tables from my DBML

sync? I would rather not...

file (XML). It provides callable command objects for each sql query.
The call substitutes template variables with its parameters, and
returns the result of the query.
I would like to get some opinions...

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
