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

Adding Bits I

I have a table, dbo.bittest, where I am testing an application response. This has this structure:

CREATE TABLE [dbo].[BitTest]
(
[insertdate] [datetime] NULL CONSTRAINT [DF__BitTest__insertd__300F11AC] DEFAULT (getdate()),
[a] [bit] NULL
) ON [PRIMARY]
GO
My application runs this code:
INSERT dbo.BitTest
(
    insertdate,
    a
)
VALUES
(DEFAULT, 'true')
GO
