some said that .NET app can run on any program where rutime exists. What is
"runtime" in this sense?
will I have to install runtime or .net framework or .NET support on an xp
machine for a .NET app to work?

Dear all,

So I have a query in which some of the select values are subqueries. The
subqueries are aggregates so I don't want to turn this into a join, it would
become too complex and postgres would have trouble optimizing things.
So my question is, is there some way to have a subselect return multiple
columns and break those out in the outer query?
Something like:
SELECT x,y,z,

Hello,
I would like to ask the about the following...
PostgreSQL allows tables resulting from subselects to be renamed with
an optional AS keyword whereas Oracle 9 will report an error whenever
a table is renamed with the AS keyword. Furthermore, in PostgreSQL
when the result of a subselect is referenced in an outer select
it is required that the subselect result be named, whereas this
is not true in Oracle. I wonder what standard SQL...

I have a performance problem with the following query and variations on the
subselect. The EXISTS version of the first example will complete in ~10
minutes. The NOT logic in both the examples makes them both keep running
long enough that a communications error is the only result returned so far.
This is a federated view computer ~160 k rows, computer_sys_id is PK .

Hi,
when creating a query with a subselect
SELECT name, (SELECT max(pop) FROM cities WHERE cities.state = states.name) AS max_pop
FROM states;
then it is not possible to sort after max_pop or use max_pop in a function or a CASE.
am I dont anything wrong or is this meant to be the case?

Dear list,
Please let me know if this is not the list to ask this kind of question.
I am trying to optimize a query that joins two relatively large (750000 rows in
each) tables. If I do it using a subselect, I can "force" the planner to choose
the fastest path. Now, my question is:

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...

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...

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...
