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.

Question of the Day

The New Log File

I have a detached database from SQL Server 2019, called TDE_Primer. This database had a 100MB data file and a 73MB log file. The log file was lost, so I need to run this code: 

USE [master]
GO
CREATE DATABASE [TDE_Primer] ON 
( FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL15.MSSQLSERVER\MSSQL\DATA\TDE_Primer.mdf' )
 FOR ATTACH_REBUILD_LOG
GO
How big is the new log file?
