Hi all,
I've been digging this problem almost 3 days now.
I created some 'normal' views and then join them all together to
create a materialized view but I got this error message:
"Subquery expressions not allowed here"
I use subqueries *only* in 'normal' views.

Do not trust values returned by materialized views under SQL Server
without frequently checking underlying tables!!!
I already posted this message under microsoft.public.sqlserver.server
and I'm amazed nobody from Microsoft answered about this problem. By
inserting lots of data into our two main tables for about 30 minutes,
we can fail our materialized view that performs a count_big on those
two tables.
Executing (after of course...

want the tables to have any enforced relationship. Is this possible
without having to do a CREATE TABLE and an INSERT?

Hi,
I first created a materialized view that was based on the org striped views like po_headers hence the automatic refresh was not happening.
After automatic complete refresh, the materialized view was showing null records.
Hence I based the materialized view on "_all" tables and then based a view on this materialized view and this view I made org striped.
In the materialized view , I was refering to...

Hi All,
I need to know the best way to set up a datawarehouse/materialized
view for doing statistics/graphs in Access. My crosstabs and unions
are getting too complicated to crunch in real time.
Should I use a make-table I run after each update?
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...

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....

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...
