various SQL dialects), but have very little experience with MS Access or
VBA, and am having trouble figuring out how to even get started with the
following seemingly simple task...
I have a table with a composite primary key made up of three columns. The

column. Values from several...

I have a data grid that takes data from a data table, and in
visualstudio.net, I cannot find the error in the debugger at why I am
not able to see my datagrid when querying data for a specific date when
I step thru the code while debugging. ON strSQL when mousing over the
variable, it indicates its empty. Just can't find where or why it is
empty.

I would like to know if there is some code and/or function that will give me a way of retrieving a certain text string from a data table that I have established in MS Access. The text in question is isolated by return carriages. I look at the Left/Right/Trim Functions; howver, neither of these could singularly accomplish what I need to do. Can someone help?

I am attempting to use triggers to add some simple auditing to my database structure (SQL Server 2005). I am running an ASP with this so I have many databases (dozens) with identical structure. My problem is that as we create new databases and tables, we have never paid attention to column ordering. Who cares right? Well triggers seem to care if you need it to key off a change in a specific column in a specific data table. I do not see any...

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.

Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
