SQL Server Trace Flag 272 : Geek City: Lost Identity

I too used to belong to the crowd thanking Microsoft for the IDENTITY column type, I came from an MSACCESS background around about the end of SQL Server 7 (sic) and I was relieved to find I didn’t have to do any tedious „mucking around“ with identity value tables.

Of course, I also knew that there is no such thing as a free lunch and that SQL Server must be doing some housekeeping for me so it couldn’t be as performant as it would be with „raw“ data. But it was a heck of a lot faster than any T-SQL solution.

In SQL Server 2012 Microsoft, bless their cotton socks, „improved“ the IDENTITY column type and, naturally, in some minds broke it. Microsoft weren’t (all) born yesterday so they added a Trace Flag to enable you to get the old behaviour back. Nice. Here are some details:
