How would one translate the following query into DAL - or should I use
executesql (I would like to use the query in SQLFORM.grid):

select B.title, A.title, similarity(A.title, B.title)
from
us2006_2010 B
left join akb_articles A on (A.title % B.title)
where
    B.id in
                (select A.id from us2006_2010 A
                left join akb_articles B on A.ltitle = B.ltitle
                where B.title is null)
order by similarity desc

The shortened result looks like this:

B.title1 |  A.title1 | 0.960526
B.title2 |  A.title2 | 0.905263
B.title1 | A.title3  | 0.511905
...
