Prior to SQL Server 2016 the trace flag –T8048 is used to upgrade (only) NUMA partitioned, CMemThread objects to CPU partitioned based objects. Keep in mind that the vast majority of CMemThread objects (SQL 2005, 2008, 2008 R2, 2012, 2014, Azure DB and 2016) are not partitioned. Trace flag –T8048 longer exists in SQL Server 2016.

When SQL Server applies simple parameterization to an ad-hoc statement, it makes a guess about the data type of the replacement parameter. For the time being, let’s look at some examples using the Stack Overflow 2010 database on SQL Server 2019 CU 14. The bigint type isn’t used for server-side parameterization. ) ; GO.

I would like to share a couple of recent examples that help illustrate how using deprecated SQL Server features continues to bite us. The system table sys.sysprocesses was replaced way back in SQL Server 2005 by a set of dynamic management views (DMVs), most notably sys.dm_exec_requests , sys.dm_exec_sessions , and sys.dm_exec_connections.

It's almost always better to explicitly parameterize statements, rather than relying on the server to do it. In any event, it would be an unusual workload that does not contain at least some parameterized statements server-side.
