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 ?

Greetings All, I have read many upon many articles here regarding GUID
data types and uniqueness. There have been many opinions regarding
the effectiveness of GUID's and when they should/should not be used.
However, every article strongly implies, if it does not state it
outright, that GUID's are always unique. My question is this, what...

Obviously you can tell that each plugin object will have...

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...

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.

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. ...
