How to Delete MSSQL Table Datetime GETDATE() Columns if they are One Year Old or Older Using PHP


My column is named order_date and the data for it is:

datetime NOT NULL DEFAULT GETDATE(),

This will make data appear as:

Apr 8 2014 3:24PM

I am wondering what PHP Query I can use to delete any rows in this MSSQL table if they are one year old or older.

I would also like a way to test if this works. (IE: Modifying a current row's order_date column to make it a year older.)

If anyone can help me with this it is greatly appreciated. T


Solution

  • delete from tracking_orders where DATEDIFF (year, order_date, GETDATE()) > 1
