Compare timestamps then delete

What I am trying to do is create a stored procedure that compares a the current datetime to a datetime field already added to a table. I also want it to compare the two and if the old data that is collected in the table is over 6 months old I want it deleted.

Someone please help

Will this function automatically change with each month. So I don't have to plug in the month everytime it changes.|||

datediff() gets the difference between the start data and end date. the "mm" signifies you're trying to get the difference expressed in number of months. getdate() is a function that returns the system date.

essentially, you're deleting the record if the difference between the datefield (content of your field) and the system date is more then 6 months ... if you need to include 6 months and older, do a "=>" instead
