Question of the Day

Comparing Images

I am building an ETL process between these tables in SQL Server 2022 set to 160 compatibility level:

CREATE TABLE Image_Staging
( imageid     INT NOT NULL CONSTRAINT Image_StagingPK PRIMARY KEY
, imagestatus TINYINT
, imagebinary IMAGE);
GO

CREATE TABLE Images
( imageid       INT NOT NULL CONSTRAINT ImagesPK PRIMARY KEY
, imagestatus   TINYINT
, imagemodified DATETIME
, imagebinary   IMAGE);
GO
I want to run this query to check if the images already loaded exist. This will help me decide if I need to insert or update an image. What happens with this query?
SELECT i.imageid
FROM
  dbo.Image_Staging AS ist
  INNER JOIN dbo.Images AS i
    ON ist.imagebinary = i.imagebinary;
