SQL Server Delete记录大于去年的这个时间

Question

I'm using SQL Server 2012. I need to delete data that is greater than this time last year.

So far example, delete any records greater than 28/11/ 2015 .

This is rolling though and will be part of a SP that will run each day, so everyday it checks the current date and deletes. What is the best way to do this?

DELETE tblmytable
where MyDateField > GETDATE ()

How do I change to say > Today from last year?

Answer 1

Use dateadd

DELETE 
from tblmytable
where MyDateField > dateadd(yy, -1, GETDATE ())

Answer 2

Got it, this is the answer:

Delete tblmytable
where MyDateField > DATEADD(year, -1, GETDATE())

Answer 3

You can try this:

delete from table
where dateField > dateadd(yy, -1, getdate())
