I have a table that contains data from different months. I am trying to retrieve all the records that exist in the current month but not in the previous month. This is my code, but need help.
WHERE  ReportAsOfDate = '9/30/2018' AND
[EntryId] NOT IN
    (SELECT * 
     FROM T1 WHERE ReportAsOfDate = '8/30/2018')
