Question

I need to count repeated rows but only show them in results if at least one of them has status = ‘new’.

______________
URL  |  Status
--------------
A       new
A       seen
B       new
C       seen

should echo:

___________
URL  |  SUM
-----------
A       2 (counts both the seen one and the new one because there is at least one nwe)
B       1   

My idea is basically to count the repeated URLs and RIGHT JOIN it with the same table but only rows with Status = ‘new’ so that remaining rows disappear.

SELECT `userFlags` distinct(URL) WHERE Status = "new"

How do I add these conditions to the joining table and how is it called?

EDIT

I added Status = “new” to the query, how can I add distinct(URL) or nest the whole query on it?

SELECT userFlags.URL, COUNT( * ) AS SUM
FROM  `userFlags`
RIGHT JOIN `userFlags` as u2 ON u2.Status = "new" AND userFlags.URL = u2.URL
GROUP BY u2.URL
ORDER BY SUM DESC 

Answer 1

Try this :

Select userFlags.URL,Count(Status) AS SUM  from userFlags
where Status = "new" 
group by userFlags.URL

Edit

Select userFlags.URL,Count(Status) AS SUM  from userFlags
where userFlags.URL in 
    (Select userFlags.URL from  userFlags where Status = "new" )
group by userFlags.URL
