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); GOI 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;See possible answers
