I was wondering if there is or there could be some way to pass a generator an
optional starting index so that if it supported that slicing could be made
more efficient. Right now if you do use a generator and do a or any
other kind of slice it reads all the values up to 100 also.
I know a lot of generators have to do all previous parts before they can do
the next part but it would be a nice optimization that can start at any index

I am trying to understand how the data in sql server is stored and
also regarding fill factor and page splitting.
1) My first question what is the difference between Index pages and
Data pages.
and how are they different for clustered and non clustered indexes and
heap tables.
2) What is the relation between index and data pages.

Hi,
I have a table with 10M records and col A has a index created on it.
The data on that table has the same value for col A on all 10M
records. After that I insert diferent values for that column but my
queries do not use the index I created for that column.
Is there any way I can force the usage of the index or to ommit a
value on the index creation, like 0 (zeroes) or spaces?
Thanks in advance,
André Queiroz

Helpful folks,
Most of my previous experience with DB2 was on s390 mainframe systems
and the optimizer on this platform always seemed very predictable and
consistent. Since moving to a WinNT/UDB 7.2 environment, the choices
the optimizer makes often seem flaky. But this last example really
floored me. I was hoping someone could explain why I get worse
response time when the optimizer uses two indexes, than when it uses
one. Some context:

I have a table where fields 1 and 2 make up the primary key.
Because of this, I have a unique composite index on fields 1 and 2 (as
required by DB2). Now my question is: Fields 1 and 2 are also
separate foreign keys to two other tables. I have read that it is
always a good idea to create indexes on foreign keys. Should I create
single indexes on each of these fields? Or is that not necessary since
they are already part of a composite...

Every Python programmer gets this message occasionally:
IndexError: list index out of range
The message tells you where the error occurred, but it doesn't tell you
what the range and the offending index are. Why does it force you to
determine that information for yourself when it could save you a step
and just tell you? This seems like a "no-brainer" to me. Am I missing
something?

I have done a fair bit of searching, but haven't yet been able to find
an explanation as to why one would set "ignore nulls" to "yes" when
creating an index. I understand what it does (I think), but I'm
looking to understand what scenario might prompt either setting (yes
or no). Any clarity you can provide is much appreciated! Thanks kindly.

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:

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 am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
