T-SQL Challenge with SQL Server 2012’s Sequence ObjectCommented on: 4 years ago
(December 16, 2010)
Most efficient way I can think of is to have the sequence INCREMENT BY 2 each time, and insert (NEXT VALUE FOR dbo.Seq1) and (NEXT VALUE FOR dbo.Seq1 + 1) into key1 and key2 (respectively) in T1....

Most of the information I’ve provided was pretty basic or elementary – along with some additional guidelines for things to watch out for when managing backups.
