Question

Sorry, for unspecific title.

I’m working with MySQL on PHP.

These are my tables:

+++++++++++++++++++++++  
|........thread.......|  
+++++++++++++++++++++++  
|.id.|..title..|..ok..|  
+++++++++++++++++++++++  
|.45.|.baslik.|...1...|  
|.53.|.baslik.|...0...|  
|.56.|.baslik.|...1...|  
+++++++++++++++++++++++  

+++++++++++++++++++++++++++++++++  
|............comment............|  
+++++++++++++++++++++++++++++++++  
|.id.|..text..|.ok.|.thread_id..|  
+++++++++++++++++++++++++++++++++  
|.1..|.falan..|.0..|....45......|  
|.3..|.filan..|.1..|....56......|  
+++++++++++++++++++++++++++++++++  

What I need is to get all checked (ok=1) rows of “thread” table with row count providing equality of thread.id = comment.thread_id and comment.ok=1.

When I use the following query, I get all count of comment checked or unchecked.

select thread.*, count( comment.thread_id ) as countComment from `thread` left join `comment` on thread.id=comment.thread_id where thread.ok='1' group by thread.id

Output I want to get must be like following one.

++++++++++++++++++++++++++++++++++++  
|.id.|.title..|..ok.|.commentCount.|  
++++++++++++++++++++++++++++++++++++  
|.45.|.baslik.|...1.|......0.......|  
|.56.|.baslik.|...1.|......1.......|  
++++++++++++++++++++++++++++++++++++  

Thanks,

Try this:

LEFT JOINcommentON thread.id = comment.thread_id AND comment.ok = '1'
