As we're on this topic in another thread right now:
Say I have a SELECT query from more than one table and with some =
conditions, does it matter in what order I enter the tables in the FROM =
clause and in what order the WHERE conditions appear in my query? Or =
does it make any difference if I use WHERE or HAVING? (I see that MS =
Access likes those HAVINGs...)
Of course my tables contain (maybe very much) more than some 100 records...

I apologize if this has been asked before- I searched google but could
not find a concrete answer.
I recently inherited a database whose t-sql code is written in a format
that I find difficult to read (versus the format I have used for
years).
I have tested the queries below using the SQL Profiler, and both have
identical costs. Is there any advantage of one format over the other?

I am starting an encryption project for my database and I'm performing
some tests on decryption speed. A lot of my application queries use a
LIKE parameter in the WHERE clause. To keep from changing my
application I am performing all the work on the back-end; creating
views, triggers and UDFs to encrypt/decrypt the data. A problem has
arisen around the LIKE parameter, though.
Currently:
SELECT SSN, FNAME, LNAME FROM USERS WHERE LNAME...

Hi,
Sometimes, I write = instead of == in if conditions by mistakes. Is
there any way the gcc compiler can give me a warning?
Best wishes,

i've got an app that needs to connect to sql server and login with a
useName/password. currently, my app saves this info in an XML file in plain
text (i.e. no encryption). everytime the app is opened, the XML file is read
and the userName/password used to establish the sql connection. is this the
normal way of doing things, or is it smarter to save these set tings
elsewhere, like the registry? if saving to XML is deemed appropriate, should...

Basically i am curious as to where everyone stores there database details for ASP.NET apps?
When developing controls i usually stored it in the web.config file.
Then i move it to a internal private property that is only acessable from my DB classes.
What other methods do people use?
Encryption and then store in the webconfig? or registry? or encrypt then registry?

One thing that's always puzzled me about implementing encryption on
remote asp.net apps is where to store the keys. The demo code indicate
that you include them in a configuration file, but this would seem to
defeat the purpose. If someone obtained the configuration file and
they knew the encryption method, then they could decrypt your data.
Storing them hard-coded in the app is just as bad, since it can be
disassembled. Obfuscation...

Hello,
I need help in removing if ..else conditions inside for loops. I have
used the following method but I am not sure whether it has actually

Below is an example to illustrate what I have used.

Hi,
is there a rule of thumb what is better/faster/more performant in SQL
Server 2005?
a) SELECT * FROM A INNER JOIN B ON B.ID = A.ID AND B.Cond1 = 1 AND
B.Cond2 = 2
b) SELECT * FROM A INNER JOIN B ON B.ID = A.ID WHERE B.Cond1 = 1 AND
B.Cond2 = 2

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'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
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...
