After searching for like 5 hours and playing around I have found a small way to generate it… See the following snippet:

SELECT DISTINCT
CONCAT(‘,’,build_field_name,’ AS ‘,build_field_name)
AS pivotarg
FROM aspin_build_fields
WHERE build_field_name IS NOT NULL

This generates the select statement fields so i dont see why you cant just wrapper the other sql statement with it.

That would be cool if there were… could you give an example?

Is there any way to do this dynamically?

Instead of this:

…
from (
(select count(s.id) as num, ’screenshots’ as type from screenshots s where s.site_id = 1)
UNION ALL
(select count(v.id) as num, ‘videos’ as type from videos v where v.site_id = 1)
) as foo
…

Do it with the records grouped from a table.
