CREATE OR REPLACE TRIGGER totalsalary     AFTER INSERT ON Employee     FOR EACH ROW WHEN ( NEW.Dno IS NOT NULL ) BEGIN     UPDATE Department     SET totalSalary totalSalary + NEW.salary     WHERE Dno = NEW.Dno; END ; 

but i got this error message and i dont know how to fix it

Error at line 3: PL/SQL: ORA-00927: missing equal sign  1. CREATE OR REPLACE TRIGGER SueldoTotal 2.  AFTER INSERT ON EMPLEADO 3.  FOR EACH ROW 4. WHEN ( NEW.Dno IS NOT NULL ) 5. BEGIN 

回答1:

SET totalSalary totalSalary + NEW.salary

You have a missing equal sign in the SET clause.

CREATE OR REPLACE TRIGGER totalsalary     AFTER INSERT ON Employee     FOR EACH ROW WHEN ( NEW.Dno IS NOT NULL ) BEGIN     UPDATE Department     SET totalSalary = totalSalary + :NEW.salary     WHERE Dno = :NEW.Dno; END; / 

NEW.salary

Also, this is incorrect while referencing OLD and NEW values:

:NEW.salary
