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.

Suppress an inspection in the editor

  1. Position the caret at the highlighted line and press Alt+Enter or click the Intention action icon.

  2. Click the arrow next to the inspection you want to suppress and select the necessary suppress action.
