I am relatively inexperienced with SQL, and I am trying to learn how
to analyze some data with it.
I have a table with the following information.
COMPANY ID , DATE, MarektValue
I would like to select the largest 100 marketvalues for each date in
my table. How can I do this efficiently in MySql.

Hi...
I've asked before about making an element in a schema be
able to use xhtml... I've attached my schema definition below...
What I'm curious about, is whether there's a means to add a length
restriction to the memo field in there... I want to restrict it
to say 200 bytes, including tags and all... Is that possible?
Something like the way I can do this for a string field?

I have a Table in a Typed Dataset which contains a Date field called
EventDate.
I've ensured that the field is defined as Date as opposed to DateTime in the
Typed Dataset.
When I generate an xml file from an instance of this typed dataset using the
ds.WriteXml method, all the dates come out formatted as follows:
<EventDate>2004-01-26T00:00:00.0000000-05:00</EventDate>

I have created a simple XML document, generated a schema from it (which
Visual Studio makes everything a string element). I then went through and
changed all fields that are dates to the Date data type. Now, when I use
the datagrid to edit the data in the XML file and then switch back to the
raw XML text date, the dates are formatted like this
"1973-10-27T00:00:00.0000000-06:00" and not as I expected, which are
supposed to be a simple...

Hi everyone! I'm trying to produce a periodic financial report on
projects from various departments. My database is set up with the
tables tblDepartment, tblProjects, tblPeriods, and tblBudgets -- the
first three serve the obvious function; the last table contains
foreign keys to tblProjects and tblPeriods, each record corresponding
to a project's budget for a particular period. Periods are also
grouped by years (a seperate field for...

Hi, I want to limit a date to a minDate and a maxDate -
is that possible, and how?
<xs:simpleType>
<xs:restriction base="xs:date">
<xs:
</xs:restriction>
</xs:simpleType>
I assume it is only possible with "pattern".

Hi,
i'd like to validate my XML file (see below) using XML Schema.
Now my question: is it possible to limit the occurrence of the element
b in the data element.
I mean: data can contain up to 10 b elements, but it doesn't matter how
the b elements are allocated in the elements a and c.
Any help would be appreciated -- thank you!

I've trying to write a query that seems like it should be simple but
for some reason my attempts are not working. This is really a general
SQL quesion and doesn't pertain to MySQL but I couldn't find a generic
database discussion group except on on advancement and theory and this
is really a basic query construction question.
Just say I have a table with three columns, name, date, score and
these represent the test scores for various...

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,...

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...
