Re: delete rows older than 2 years from current date
First try to build an SQL select query with a 'where clause' of the date u mentioned. Check if the data u intend to delete is selected or not. Then change the select to delete with same where clause. Test it on few rows first. If the result is as expected then change the where condition accordingly and then run it on production data. Hope this helps.
