Greetings,
I'd like to figure out some syntax for retrieving the data from a table
when I don't know all the of field names. What I do know are, the name
of the table, the names of the primary key fields, and the names of the
fields I want to use in the "where" clause of the SELECT statement. All
of the examples I've seen in my books only show how to do this by
hard-coding the names of each of the fields, i.e.,
$userid=$query_data;

What I'm trying to have done is the following:
After data is entered into a form, I want the user to click the
"Submit and print" button, which solidifies the data in the tables,
then prints a report based on the most recent data.
Do I need an autonumber column and have the report be based off the
largest record number or is there an easier way to do it? Also, I'm
not at all familiar with VBA (my small DB experience is in Perl and...

I have a subform with multiple records tied to a main record and main
form. In the subform I create and update the subform records. However,
there are other pieces of data, statistics, I want to add automatically
to the record when it is saved. I can access the data via VBA code in a
"before update" event. Any way to address the record itself and all
fields - even fields not on the form?
So far I figure I could
1) put all the...

I was curious to know what some developers out in the industry are doing when it comes to exposing Data access logic, specifically persistence. This is assuming that your not using an O/R framework or something that completely abstracts you from the persistence details.
Are you:

Hello,
I was wondering if anyone could tell me a good way to add data to a datagrid
(or it's dataset) when the user edits/adds a record in a datagrid.
Basically, I want to be able to add a username / timestamp to a record, I'm
sure there are plenty of ways to do this, but I'm sure it's been done before
and was wondering if anyone had any good proceedures they use, since I've
started using datagrids more frequently.

create the interface and implementation for a class called Book, create
objects within the class, and process transactions that manipulate (and

Is there a problem with stability when one uses too many text (memo) fields?
I'm having a problem with data from one record occasionally ending up in
another record, though apparently not through any user interaction.
I'm using SQL 7 and accessing the tables through the ODBC driver. There are
two tables with a one-to-one relationship -- TableA and TableB. TableB is
the one that's having this occasional problem. TableB has about 30 text...

I have a XML file I am working with. This file has been created by hand and I now need to develop a PHP script that will create it in the same format.
Here is what I have thus far:
$query = "select * from " . $table_name . " ORDER BY stateID ASC";
$result = mysql_query($query, $connection) or die("Could not complete database query");
$num = mysql_num_rows($result);

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...

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
