How to automatically delete records in sql server after a certain amount of time [duplicate]

Answer 1

Create a Stored Procedure to do it and then schedule the SPROCs running as explained here.

DELETE FROM myTable
WHERE timeStamp < DATEADD(Day, DATEDIFF(Day, 0, GetDate())-1, 0)

Answer 2

you can have your program do it, or set up a sql agent job.

Answer 3

You might be able to get what you want without actually deleting the records. You can add a computed column into the table to say whether the record is valid.

 IsValid as (case when getdate() - CreatedAt > 1 then 0 else 1 end)

You can also do this for key fields in the record, so you cannot find them:

_name varchar(255),
name as (case when getdate() - CreatedAt < 1 then _name end)

You can then use a view to access the table:

create vw_Logins as
    select name, . . .
    from t
    where isValid = 1;

Then, at your leisure, you can actually remove the rows if you need to for performance reasons.

EDIT:

You don't actually need a computed column, if you phrase the view as:

create vw_Logins as
    select name, . . .
    from t
    where getdate() - CreatedAt < 1;

Answer 4

You could create a SQL Job to run each day and execute a specified stored procedure.
