“Merge” style operation with literal values?

Question

I have a table containing a student-grade relationship:

Student   Grade   StartDate   EndDate
   1        1    09/01/2009    NULL
   2        2    09/01/2010         


        

Answer 1

Simply:

--Arrange

CREATE TABLE dbo.Product
(
    Id   INT IDENTITY PRIMARY KEY,
    Name VARCHAR(40),   
)
GO

--Act

MERGE INTO dbo.Product AS Target 
USING 
(
    --Here is the trick :)

    VALUES 
        (1, N'Product A'),
        (2, N'Product B'),
        (3, N'Product C'),
        (4, N'Product D')
) 
AS 
Source 
(
     Id,
     Name
) 

ON Target.Id= Source.Id

WHEN NOT MATCHED BY TARGET THEN 

INSERT 
(
      Name
) 
VALUES 
(
      Name
);
