context_id=@contextID tells the server to return 1 when the column value
of context_id is equal to the value of the user variable @contextID, and
otherwise zero. Not likely what you intend.
Apart from that, does the following, in standard SQL, represent what you
are trying to accomplish?
INSERT INTO master_context_list (Context_ID, Target_ID)
SELECT l.Context_ID, l.Target_ID
FROM targets_list AS l
INNER JOIN applicable_target_ids AS a USING (target_id);
