Usually when I create an index in the Query Analyzer, no message is
returned other than the command completed. But sometimes I get a
message than the index is being rebuilt. I have come to ignore this
message as it appears to not be an issue that needs research.
I am now doing more and more in the VB.NET environment using ADO.NET
to maniupulate SQL objects. (Using SQL7, btw.) When I need to create
an index in VB.NET code I use the...

One table I manage has a clustered index, and it includes some
varchar columns. When it is initially created, all the columns
in the clustered index are populated, and then some of the longer
varchars are populated through update queries. If the varchar
columns are stored outside the clustered structure, then it would
make sense to create the clustered index before populating the
varchar columns. Otherwise it would make sense to wait,...

Is there any advantage to doing this:

Hi,
I am curious about how php deals with the following situation where I
use an undefined index into an array. PHP seems to be behaving exactly
how I want it to but I want to make sure that it is not a fluke. It
seems like most programming languages would crash if you used an
undefined index. Why does PHP work the way it does?
My example is below

In a table design, properties window there is the Indexes/Keys tab.
I want to create a few indexes.
Row myID is the PK.
I also want indexes on rows myOne, myTwo, myThree.
In the selected index window: PK_tblName I see myID.
Do I put myOne, myTwo, myThree under that in the same index or do I
create three new indexes for the table?

A lot of detailed discussion explains the difference between clustered
and non-clustered indexes. But very few 'clarifies' why the term used
is 'clustered'. Well, once and for all, this is my take.
*** The 'CLUSTERED' adjective refers to the INDEX being clustered (set
adjacent) to the DATA.
This means if you found the index, the data is already there beside it
(you don't have to look anywhere else). From this note, everything...

Hi All,
Is it possible to create a partitioned index on a table which is not partitioned? If so what is such a partition called and please explain?
I have done some research on partitions and index partitions and this is where I hit the wall the 2nd time. As per my study there are 3 types of indexed partitions: Global index (which is on an entire partitioned table) then there is Local Index (on just the partition of the table) and then there...

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,...

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...
