Another rookie question; How to implement Count() here?

Question

I have this query:

SELECT mt.*, fordon.*, boende.*, elektronik.*, business.*, hem_inredning.*, hobby.*
FROM classified mt 
LEFT JOIN fordon ON fordon.classified_id = mt.classified_id 
LEFT JOIN boende ON boende.classified_id = mt.classified_id 
LEFT JOIN elektronik ON elektronik.classified_id = mt.classified_id 
LEFT JOIN business ON business.classified_id = mt.classified_id 
LEFT JOIN hem_inredning ON hem_inredning.classified_id = mt.classified_id 
LEFT JOIN hobby ON hobby.classified_id = mt.classified_id 
ORDER BY modify_date DESC

I need to implement a count here, to just count all rows in combination with the JOINS you see.

How should I do this?

SELECT COUNT(mt.*, fordon.* etc) FROM ? // This method wont work

Thanks

Answer 1

SELECT COUNT(*) FROM (SELECT mt.*, fordon.*, boende.*, elektronik.*, business.*,     hem_inredning.*, hobby.*
FROM classified mt 
LEFT JOIN fordon ON fordon.classified_id = mt.classified_id 
LEFT JOIN boende ON boende.classified_id = mt.classified_id 
LEFT JOIN elektronik ON elektronik.classified_id = mt.classified_id 
LEFT JOIN business ON business.classified_id = mt.classified_id 
LEFT JOIN hem_inredning ON hem_inredning.classified_id = mt.classified_id 
LEFT JOIN hobby ON hobby.classified_id = mt.classified_id) As A

Answer 2

I removed the ORDER BY, as it is not required for the COUNT:

SELECT count(*)
FROM classified mt  
LEFT JOIN fordon ON fordon.classified_id = mt.classified_id  
LEFT JOIN boende ON boende.classified_id = mt.classified_id  
LEFT JOIN elektronik ON elektronik.classified_id = mt.classified_id  
LEFT JOIN business ON business.classified_id = mt.classified_id  
LEFT JOIN hem_inredning ON hem_inredning.classified_id = mt.classified_id  
LEFT JOIN hobby ON hobby.classified_id = mt.classified_id 

Answer 3

How about simply:

SELECT COUNT(*) FROM ...

Answer 4

How about SELECT COUNT(*) FROM ... ? I'm not sure what you're trying to count.
