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.

Code: import from import mlab np # np # my dataset -simplified-x, y, z = np.mgrid [-3: 3: 100] H, -3: 3: 100h, -3: 3: 100 h] value = NP.

Look [66:,:,:] = 1 src = mlab.pipeline.scalar_field (value) src.image_data.point_data.add_array (colorvalues.T.ravel ()) (1) .name = 'MyID' src.image_data. point_data.update src.image_data.point_data.get_array () # surface, contour = mlab.pipe...
