Temporary Stored Procedures #sproc
CREATE PROCEDURE #MyProcedureName
Yes, you can create temporary stored procedures by prefixing the name of the sproc with a #. The temporary stored procedure is sort of a “leave no trace” stored procedure that is only good for your session. If you use double ## you will get a global temporary stored procedure.

DBCC CheckDB and CheckTable doesn’t check In-Memory OLTP.
Special thanks to my friend Theresa Iserman for introducing me to Jos de Bruijn the Senior Program Manager for the In Memory OLTP (Hekaton) project to help get my questions answered at PASS Summit.
So, the Hekaton – In Memory OLTP tables are perhaps one of the most amazing performance improvements to SQL OLTP in a long time. The way that they are managing data with no latches, locks or spinlocks is awesome, and the performance gains are great.
However in a recent session at Pass Summit 2016 with Bob Ward, I followed up with a question on CheckDB and In Memory OLTP tables. Since the data for these are not store in the normal SQL Server data files or even in regular pages. Bob confirmed that CheckDB (and CheckTable) does not check the data associated with the In Memory OLTP tables. I even confirmed this from Books Online in a post called “Transact SQL Constructs Not Supported by In-Memory OLTP” which stated the following:
- DBCC CHECKDB skips the memory-optimized tables in the database.
- DBCC CHECKTABLE will fail for memory-optimized tables.
