我创建了我的第一个sql触发器，

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
;

但我收到此错误消息，但我不知道如何解决它

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：

设置totalSalary totalSalary + NEW.salary

您在。 *

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;
