Question

I have two select statement like

Select author_id, count(text) from posts group by author_id

select author_id, count(text) from posts where postcounter =1 group by author_id

Is there a way to combine in a single query the two statements? Results differ in length, so it is needed to insert some 0s in the second resultset.

Many thanks for any help

Best regards,
Simone

You should be able to get this in a single query using:

Select author_id, 
  count(text) TextCount,
  count(case when postcounter=1 then text end) PostCount
from posts 
group by author_id
