Is it correct that SQL Server does not support IDENTITY(slide 29)?<p>IDENTITY property is supported from as far as I can remember: <a href="https:&#x2F;&#x2F;docs.microsoft.com&#x2F;en-us&#x2F;sql&#x2F;t-sql&#x2F;statements&#x2F;create-table-transact-sql-identity-property?view=sql-server-2017" rel="nofollow">https:&#x2F;&#x2F;docs.microsoft.com&#x2F;en-us&#x2F;sql&#x2F;t-sql&#x2F;statements&#x2F;create...</a><p>Second approach is DEFAULT with sequence.<p>CREATE SEQUENCE seq; CREATE TABLE tab(i INT DEFAULT NEXT VALUE FOR seq, b VARCHAR(100))
