Context
You could call
Activity.get
with the fieldcase_id
,tag_id
, orfile_id
. The field could specify a number or an array (e.g.array('IS NOT NULL'=>1)
orarray('>'=>100)
).Before
Specifying a filter like
case_id => array('IS NULL'=>1)
was meaningless. It led to an incorrect subquery.After
IS NULL
filtering leads to aLEFT JOIN
andWHERE the_column IS NULL
.Acceptance Criteria
IS NULL
also work.
