Hello,
given two tables:
>>> db.define_table('A', Field('asof'), Field('data'))
>>> db.define_table('B', Field('asof'), Field('other'))
I'd like to to identify all rows in A having no row with the same
'asof' in B.
SELECT A.ASOF FROM A, B WHERE A.ASOF NOT IN (SELECT B.ASOF FROM B)
What is the best way to express this in DAL?
Regards, Andreas
