well ,i didn't find correct title question, sorry that. i have 1 table store emails sent users. in table can know if user read or not email. table structure: [mailsend_id] (int), [id_user] (int), [mail_id] (int), [read] (bit) data: ;with cte ( select * (values (1, 10256, 10, 0), (1, 10257, 10, 1), (1, 10258, 10, 1), (1, 10259, 10, 0), (2, 10256, 10, 0), (2, 10257, 10, 0), (2, 10258, 10, 1), (2, 10259, 10, 0), (3, 10256, 10, 1), (3, 10257, 10, 0), (3, 10258, 10, 0), (3, 10259, 10, 0) ) t(mailsend_id, id_user, mail_id, read) in example, can see, have 4 users , 3 emails sent. user 10256 1st email - don't read 2nd email - don't read 3rd email - read i need make select on table, give [mail_id] , [number] , number represent sequential e-mails not read user. using last example: give [number] = 3, [mail_id] = 10 return user_id 10259 only. give [number] = 2, [mail_id] = 10 return user_id 10257, 20259. give [number] = 1, [mai...
