Hi everyone,
I was wondering if it is possible, to use SQL to return more than one table
at a time into a dataset. I only know the basics of SQL and so I'm not sure
if I'm just asking a stupid question. But, I'm not proud! :-)
I'm using Ado.net and I'm wanting to load a DataSet object with several
independent tables. (For those who arent ADO.net programmers, a DataSet can
hold multiple tables and the relationships and contraints...

I have an application with one main table with a jillion attributes.
There are numerous other tables, but these are either children of the
main table or lookup tables.
I am finding that I am using up all my indices on the main table to
support the relationships with all the child and lookup tables.
My question is this: would anyone suggest or caution against the use
of tables that are related to the main table in a 1:1 relationship?

I'm creating relationships between tables using VBA and ADOX. I can
create one-to-one relationships with an inner join, but I can't figure
out how to create these relationships with an outer join (specifically
a left outer join). I'm including the code that creates the
relationships with the inner join. Any help or suggestions would be
greatly appreciated.
Thanks!

Hey all, I have the following code to populate a ListView control from
my Access database. The listview is displaying a list of saved projects
that the user will be able to open, edit, or delete to work on. I know
that the DataReader is more efficient and faster than a dataset, but I
was not able to figure out how to implement it. Here is the code I have
now which works:

I'm trying to create a Crystal Report based on a strongly-typed DataSet
(that I'm populating manually instead of from a database). This is almost
working except Crystal seems to always do inner joins along the
relationships in the DataSet, but I want an outer join.
I have a table (QuestionTable) that's a list of questions. Each row
contains the question, as well as the foreign key to a row in AnswerTable

I am new to Access, trying to figure it out on my own.
I am trying to create a form to input the same information in 3
different tables. The 3 tables each have a different number as the
primary key, although they each do contain the other 2 numbers in
their tables.
I have been unsuccessful and am wondering if perhaps my relationships
are inaccurate.

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...

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,...
