Code Inspection: Suspicious code in triggers
Reports incorrect usages of transition table variables in triggers.Example (HSQLDB):
CREATE TABLE foo(a INT); CREATE TRIGGER trg AFTER DELETE ON foo BEGIN SELECT * FROM NEW; END; CREATE TRIGGER trig AFTER INSERT ON foo REFERENCING OLD ROW AS newrow FOR EACH ROW WHEN (a > 1) INSERT INTO foo VALUES (1)In HSQLDB, DELETE triggers may be used only with the OLD state while INSERT triggers may have only the NEW state. So, in the previous example, NEW in
SELECT * FROM NEW;will be highlighted as well as OLD in
REFERENCING OLD ROW AS newrow.
