If the user want to archive data older than 30 than @numberofDay should convert into date like 11/03/2013.
They want to pass in days as int and the process should convert that into day.

Any help would greatly appreciate.

Declare @NumberofDay INT = 30

-- No

@NumberofDay should be something like '11/03/2013'


DELETE FROM MyBilling
OUTPUT deleted.[__$start_lsn], deleted.[__$seqval], deleted.[__$operation], deleted.[__$update_mask], deleted.[BillingDetail_ID]
INTO ArchiveAudit.MyBilling_CT ( [__$start_lsn], [__$seqval], [__$operation], [__$update_mask], [BillingDetail_ID]

WHERE (CONVERT(CHAR(8), [Effective_date], 112) < @NumberofDay ) -- This some how become '11/03/2013'

Do you want a date that is @numberofDays less than today?


declare @numberOfDay int; set @numberOfDay = 30
select dateadd(day, datediff(day, 0, getdate()), -@numberOfDay)

OUTPUT:
2013-11-03 00:00:00.000


So you probably want:

WHERE Effective_date < dateadd(day, datediff(day, 0, getdate()), -@numberOfDay)
