Using "SELECT * " is a bad practice even
when using a VIEW instead of a table?
I have some stored procedures that are
identical with the difference of one statement
in the WHERE clause. If I create a single View
and specify also in this View the WHERE clause
that is common in these stored procedures, I
will have the new stored procecures changed to

Here is my problem.
I need to display a table about which I have no information except the
table name. Using metadata I can somehow show the column names and
record values.
But my table has 1 million rows and if I do a select * then I do get
1 million rows.

Hi,
I've read the former postings but was not able to solve my problem:
I have a Summary Table (or MQT as you like it) and the query optimizer
does not seem to use the summary table.
I run the following commands:
set current query optimization 9;

Using a base table, a MQT table was created. With optimization - when
querying the base table with calcuation that are already completed in
the MQT - I would assume the optimizer would use the MQT table instead
of the base table.
What causes the optimizer to use the MQT tables rather than the tables
as defined by the query? Is there a way to "encourage" use of the MQT
tables?
Thanks.

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
