Question

Consider the query:

SELECT n.nid, 
    (select count(*) as count from view_log where id = n.nid) AS the_count,
    (the_count + 1) as the_bumped_count
   FROM node n

When I run this, I get Unknown column 'the_count' in 'field list'. Is there any way around this? It seems like the_count should be visible in the query and available for use, but apparently not. BTW, I also tried SUM(the_count, 1), but that also failed. Thanks!

I think this would work as well, and only require you to count once:

SELECT nid, the_count, the_count+1 as the_bumped_count
FROM (
    SELECT n.nid,
        COUNT(v.*) the_count, 
    FROM node n
       LEFT JOIN view_log v on n.nid = v.id
    GROUP BY n.nid
) t

Or to go back to your syntax:

SELECT nid, the_count, the_count+1 as the_bumped_count
FROM (
    SELECT n.nid,
        (select count(*) as count from view_log where id = n.nid) AS the_count
    FROM node n
) t

Good luck.
