Can you please tell us the data type of Search_Date?
And if it is not DATE or DATETIME then please post an example on how the values are formatted in that column.

No, you're never too old to Yak'n'Roll if you're too young to die.

DELETE FROM dbo.Table_Name WHERE Search_Date < DATEADD(MONTH,DATEDIFF(MONTH, 0, GETDATE())-2,0)

if you want to consider start of day (0000 hrs) as boundary value

nope this will search from first date of the previous 2 month period


DELETE FROM dbo.Table_Name WHERE Search_Date < DATEADD(MONTH,DATEDIFF(MONTH, 0, GETDATE())-2,0)

see this simple example

DECLARE @dateval datetime

SET @dateval='20120815'

SELECT DATEADD(MONTH,DATEDIFF(MONTH, 0, @dateval)-2,0)

the datediff part returns number of months elapsed from basedate (1 jan 1900) till current datemonths. then it subtracts 2 from it to reach two months prior to current month. adding this month value again to basedate using dateadd causes it to return 1st of that month

see this for similar logics
