mysql - show multiple result of count -

-

I am trying to show the count of idParent in the child table where is the original table IDPorte of is equal to idContent of the original table.

SQL Request: 

  Select Count (idpent) from content_copy_f idContent where content_copy_f.idParent (select idContent from content)

But it does not display every count of each idParent in each line, with its result it shows a single line.

Try this query: - 

  SELECT COUNT (idParent) , IdContent from content_copy_f where content_copy_f.idparent IN (Select content from content) content by IDContent;

Hope this will help you.
