Hi,
Is there any replace for "Select @@identity" that could return "just
inserted" GUID as a primary key?
Has anyone tested what's faster, working with Guid or Autonumber ?

I know that this should be impossible, yet it is happening...
I have some c# code that uses a method scoped variable of type Guid. The
code assigns Guid.NewGuid() to the variable. This value is then used as a
primary key in a database table.
I have seen two occasions over the last 6 months where after a certain point
in time the same Guid is always generated by the code.
I have verified that there is nothing static, the code is...

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.

How can I return the new id that is created when an insert command is used?
for example:

I tried this and received an error "System.NullReferenceException: Object

Although the insert does take place. How would I do this? I can't create a

Hi all,
is there a method or property of a class that will

In Access, newID returns a unique for the table. In SQL Server, newid()
returns a GUID - unique in the world. I do not need or desire that
complexity. Is there a way to get a simple unique int on the table in
SQL Server?

Hi there,
I need to create a unique identifier for my own internal needs and am happy
to rely on "Guid.NewGuid()" to pull this off. I'd like to know if .NET
offers any competing alternative however. Perhaps there's something with a
richer set of functions for instance and it might offer potential advantages
over a GUID. Am just exploring the possibilities for now. Thanks in advance.

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,...
