Stored proc to remove records older than N days

Question

I want to create a two stored procedures that will remove records older than N days from a stgging database.

Both stored proc will call in a package to cleanup data older than N days.

Stored proc A will remove records from table A.Fullimport & stored proc B will remove records from table B.weeklyimport.

The same stored proc will remove all records from error table where there is not a record in table x and table Y.

Both stored proc will accept input variable @Cleanupdays.

Answer 1

Basically, you'd have to write something like:

CREATE PROCEDURE dbo.CleanupTableA (@CleanupDays INT)
AS BEGIN  
   DELETE FROM A.Fullimport
   WHERE DATEDIFF(DAY, SomeDateField, GETDATE()) > @CleanupDays
END

or something like that - without the exact table structures, it's really hard to get this totally correct.....

The DATEDIFF function can give you the difference between two dates in various units - e.g. in days, as you want it (could also be weeks, months, year etc.). All you basically have to do is delete all the rows that have a DATEDIFF to today's date that is greater than the value of @CleanupDays passed into the stored procedure.

I don't quite understand what you meant about the error table.... you might need to clarify that a bit...
