Symptoms
When the SQL plan has interleaved execution enabled and uses the OPTION (OPTIMIZE FOR) clause, the table-valued function (TVF) that uses a parameter passed in the same SQL statement gives incorrect results on the first run.
Resolution
This problem is fixed in the following cumulative update for SQL Server:
Cumulative Update 19 for SQL Server 2019
Note Here is an example of not using interleaved execution after you install this cumulative update:
DECLARE @start smalldatetime
SELECT count(*) FROM dbo.GetData(@start)
OPTION (OPTIMIZE FOR (@start = '2022-05-23T06:00:00'))
CREATE FUNCTION [dbo].[GetData]
(
@start datetime
)
RETURNS TABLE AS RETURN
SELECT t.id FROM dbo.TestTable t
WHERE t.testdate >= @start
GO
CREATE TABLE [dbo].[TestTable](
[id] [int] IDENTITY(1,1) NOT NULL,
[testdate] [datetime] NULL
) ON [PRIMARY]
GO
