How can I use a SQL UPDATE statement to add 1 year to a DATETIME column?

Question

I want to add 1 year to a datetime-type column in every single row in a table. Adding using an UPDATE statement is easy for numeric types. ex:

UPDATE TABLE S         


        

Answer 1

There is in fact a DATEADD statement in T-SQL, you can find it here

UPDATE Procrastination SET DropDeadDueDate = DATEADD(yyyy,1,DropDeadDueDate)

EDIT: You could use year, yy, or yyyy for the first argument of DATEADD.
