When using a Guid as your primary key in a table, does it make
sense to make it a clustered index?
Thanks,

Hi,
The following is from MSDN.
"A GUID is a 128-bit integer (16 bytes) that can be used across all
computers and networks wherever a unique identifier is required. Such
an identifier has a very low probability of being duplicated."
My application will crush if I have two or more number that are
identical, so I need to know do I need to worry about this"

Is it possible to generate a 20 byte integer from a GUID that is "unique
enough" ( just like a GUID is not truly unique , but is "unique enough" ).
We identify transactions with GUIDs , but a partner web service has a 20
byte limit on transaction ID passed.

Has anyone tried using inet or cidr for storing GUID (or for storing
128bit numbers or hashes or similar stuffs)? It has a nice property in
that one can use hexadecimal notation (like
'FEDC:BA98:7654:3210:FEDC:BA98:7654:3210') when inserting it. Plus IPv6
is 128bit too.

I have a column named "ID" and its type is "uniqueidentifier" in SQL Server
2005 Express.
this column is the primary key and its default value is "newid()" in SQL
Server.
I have generated a DataSet in C# that has this column but its default value
is DBNull what can I do to make the default value be the return value of
this function ( or I want the Id be generated by default in the DataSet)?
System.Guid.NewGuid()

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:

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,...
