Let's say I have an html form with 20 or 30 fields in it. The form
submits the fields via POST to a php page which updates a table in a
database with the $_POST vars. Which makes more sense?
1) simply UPDATING the values for all fields in the table, whether or
not any particular field has actually changed
2) running a second SELECT statement and comparing the $_POST vars to
the returned values, and only UPDATING those that have...

Hi everybody-
I'm helping a friend with a music database. She has an old one and is
creating a new one. She wants to compare records and fields in the old
database with records and fields in the new database. For instance,
her old database has a table with Band Info in it. Her new database
also has a table with Band Info in it but slightly different. I was
wondering if there was an easy way to compare the fields from similar
tables in...

Hi
I'm hoping somebody can help me with the following problem that has occurred
to me.
Suppose I have two tables in an SQL Server database. Let's call these tables
A and B. Assume that A has two fields: a primary key and another holding a
string. In table B there are three fields: a primary key, a foreign key
(which links to the primary key in A) and other field holding a string.

Hiya,
How do i retreive fields with similar values from 2 tables?
I tried to use
(1) "SELECT * FROM $table1 as o , $table2 as p WHERE o.name like
'%p.name%'";
but it retrieves nothing at all.
(2) "SELECT * FROM $table1 as o , $table2 as p WHERE o.name like p.name";

I have an application which contains an Access database with linked
tables that point to another database within the application. The
problem I have is that when the user installs the application, I need
to update the table links so that the paths are correct for the install
directory. Is there an easy way to accomplish this?
I'd really like to avoid duplicating the data in the linked tables, but
if updating the links is too much work,...

I have three tables: Courses (Key is Autonumber Course Number, also have
Text Course Name); Instructors (similar fields); and Courses and Instructors
(have a combination of the four fields).
Currently, if I manually select the course from the drop-down box, the
Course Number, and the same with the Instructor fields, then I can save the
record. If the Course Number doesn't match the Course Name, though, I'm out
of luck.

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,...
