AS File Table Applies to: SQL Server 2012 through SQL Server 2017. You do not specify columns because a File Table has a fixed schema.
Using NEWSEQUENTIALID also helps to completely fill the data and index pages.
The Uuid Create Sequential function has hardware dependencies.
On SQL Server, clusters of sequential values can develop when databases (such as contained databases) are moved to other computers. You can use NEWSEQUENTIALID to generate GUIDs to reduce page splits and random IO at the leaf level of indexes.
When using Always On and on SQL Database, clusters of sequential values can develop if the database fails over to a different computer. Each GUID generated by using NEWSEQUENTIALID is unique on that computer.
When a GUID column is used as a row identifier, using NEWSEQUENTIALID can be faster than using the NEWID function.
This is because the NEWID function causes random activity and uses fewer cached data pages.
The Sql Server Newsequentialid Error Validating The Default For Column error may be caused by windows system files damage.
The corrupted system files entries can be a real threat to the well being of your computer.
