SSC Clinic: Can Implementing "Optimize for Ad Hoc Queries" Boost Performance for the SQLServerCentral.com and Simple-Talk.Com SQL Servers?
With the introduction of the instance-level option “optimize for ad hoc workloads” in SQL Server 2008, DBAs have a tool to deal with a problem known as plan cache pollution, or plan cache bloat. It’s often caused when one-time use ad hoc queries are sent to SQL Server from Object-Relational Mapping (ORM) solutions, such as LINQ, NHibernate, or Entity Framework. The problem can prevent SQL Server from using its available memory optimally, potentially hurting performance.

Question of the Day
The Read Committed Snapshot Isolation behaviour
I am currently working with Sql Server 2022 and AdventureWorks database. First of all, let's set the "Read Committed Snapshot" to ON:
use master; go alter database AdventureWorks set read_committed_snapshot on with no_wait; goThen, from Session 1, I execute the following code:
--Session 1 use AdventureWorks; go create table ##t1 (id int, f1 varchar(10)); go insert into ##t1 values (1, 'A');From another session, called Session 2, I open a transaction and execute the following update:
--Session 2 use AdventureWorks; go begin tran; update ##t1 set f1 = 'B' where id = 1;Now, going back to Session 1, what happens if I execute this statement?
--Session 1 select f1 from ##t1 where id = 1;See possible answers
