Exploring Parameter Sensitive Plan Optimization in SQL Server 2022

  • Article

PSPO (Parameter Sensitive Plan Optimization) is a SQL Server feature that improves query performance by accepting varied data sizes based on the runtime parameter value(s) specified by the customer. It deals with the situation in which a single cached plan for a parameterized query isn't the best option for all potential incoming parameter values. Non-uniform data distributions exhibit this phenomenon. When using PSPO, SQL Server keeps several execution plans for a single query, each one customized for a particular parameter value. With the help of this feature, numerous execution plans for a parameterized query are generated, each of which is tailored for a certain range of parameter values.

Dropping a Logon Trigger

I created this trigger for testing on SQL Server 2022:

CREATE TRIGGER checksteve
ON ALL SERVER 
FOR LOGON  
AS  
BEGIN  
IF ORIGINAL_LOGIN()= N'ARISTOTLE\Steve'
 PRINT 'Steve logged in'
END;  
GO
Now I want to drop it. What do I run?
