Question

I want to do the same thing with DELETE as I do with SELECT. I can’t really figure out how the join works with delete?

SELECT *
FROM table1 1 inner join table2 2 
 on 1.Id= 2.Id inner join table3 3 
 on 3.id=2.Id
WHERE 3.id= @Id 

Answer 1

This should work:

DELETE table1 
FROM table1 t1
INNER JOIN table2 t2 
on t1.Id= t2.Id
INNER JOIN table3 t3 
on t2.Id= t3.Id
WHERE t3.ID=@ID
