I am trying to do a inner join with one data extension and the data view _sent, inner join on subscriber key from _sent and contactid from data extension. I want to fetch the max event date i.e the last sent date from _sent data view. But whenever I am using the max aggregate function, its throwing an error as "An error occurred while checking the query syntax. Errors: Column 'C6300865.Contact_BrandPref_CCV.createdon' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause." It is working without the max function.
Can anyone help what wrong I am doing in this below query:
