To keep track of how many fruits my visitors buy, I use a mySQL database
(2 columns: "fruit" and "quantity")....so can we make these following
mySQL queries work somehow?
(visitor buys 5 apples):
replace into fruit_database set fruit = 'apple' , quantity = quantity +
5;
(visitor buys 7 apples):
replace into fruit_database set fruit = 'apple' , quantity = quantity +

In Access, if I want to update one table with information from another,
all I need to do is to create an Update query with the two tables, link
the primary keys and reference the source table(s)/column(s) with the
destination table(s)/column(s). How do I achieve the same thing in SQL?
Regards
Colin

After much frustration I was able to update my data store via code only.
Using the data adapter was the only way I was able to set up all the objects
written in my code. Basically, I cheated by creating an adapter and then
copy, paste, modify it's code to suite my needs. This was the end result:
Private sub updateTable( )
Dim myData As DataSet
'Command is a form level oledbcommand object
Dim Adapter1 As New OleDbDataAdapter(Command)

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

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,...
