I need to extract data from this table to find the lowest prices of
each product as of today. The product will be listed/grouped by the
name only, discarding the product code - I use SUBSTRING(ProductName,
1, CHARINDEX('(', ProductName)-2).
I can get this result, but I had to use several views (totally
inefficient). I think this can be done in one efficient/fast query,
but I can't think of one.
In the case that one query is not...

The following stored procedure is taking too long (in my opinion). The
problem seems to be the SUM line. When commented out the query takes a
second or two. When included the response time climbs to minute and a
half.
Is my code that inefficient or is SUM and ABS calls just that slow?
Any suggestions to spead this up?
Thanks,

I have a stored procedure that suddenly started performing horribly.
The query plan didn't look right to me, so I copy/pasted the code and
ran it (it's a single SELECT statement). That ran pretty well and used
a query plan that made sense. Now, I know what you're all thinking...
stored procedures have to optimize for variable parameters, etc.
Here's what I've tried to fix the issue:
1. Recompiled the stored procedure
2. Created a new,...

I have a number of very common queries that the optimizer plans a very inefficient plan for. I am using postgres 7.2.3. I vacuum hourly. I'm wonderingwhat I can do to make the queries faster.
Here are the relevant tables:

In Microsoft Access I can write a query that includes the criteria:
Between Date()-7 And Date()
to retrieve the records from a table that fall within the last week.
I'm trying to write a procedure to do this in VB.NET (2005 Express
Edition). But I always get the message that the Jet database engine
does not recognize the syntax (of the Date function I assume). I've
also tried Now() and it works but only by itself. I seem to add or

I'm struggling to find the best query from performance point of view
and readability for a normalized DB design.
To illustrate better my question on whether normalized designs lead to
more complex queries yes or no, I have prepared an example. The example
is a database with the following tables:
*table person with fields:
-persid: autoincrement id
-name: name of the person
*table material with fields:
-materialid: autoincrement id

Background: Access 2003 (converted from A97 DB recently), database is
split into FE/BE with the FE residing on client machine.
I've got a question about how I can possibly optimize a query I've
built. This may seem relatively straight forward to some of you more
experienced programmers, but I'm almost entirely self-taught. This
means that I have some gaps in my knowledge and sometimes go about
doing things the hard way never knowing...

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,...
