Can "uniqueidentifier" value be generated based on Algorithm ? - SQL Server

Hi,

Can we create an "uniqueidentifier" value based on certain Algorithm ? I want to make sure that all the values of the "uniqueidentifier" column must satisfy one Algorithm - for data integrity. Please do NOT provide about Encryption.

Thanks

Create the column as type "UniqueIdentifier" and then when you add to it you can call "newid()"

newid() is a build-in SQL function that will make sure the GUID is globally unique or at least unique at the server level - depends on your setup.

If you are using a coding language, there are ways to produce GUID's there too.

You don't need to have a column of type 'uniqueidentifier' in your DB table, you can just make it 'int' (or something else).  Then just make that column the primary key and define it as 'unique' in the table designer.  Whenever you add a row, just supply a new ID along with your other data (ensuring it's unique by whatever method you use).

Do you have the algorithm to generate your IDs, or do you need one?
