Description:
If two items in an IN expression are separated by a newline instead of a
comma, those items will be ignored with no error.
CREATE TABLE testing (id varchar(1));
INSERT INTO testing VALUES ('1'), ('2'), ('3'), ('4'), ('5');
-- Missing comma produces a syntax error
SELECT * FROM testing WHERE id IN ('1' '2', '3');
-- Unless there is a newline
SELECT * FROM testing WHERE id IN ('1'
'2', '3');
