ORA-00927: 缺少等号

Question

我正在创建我的第一个 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，但我不知道如何修复它

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

Answer 1

SET totalSalary totalSalary + NEW.salary

您在 SET 子句中 缺少等号 。

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

此外，在引用旧值和新值时这是不正确的：

:NEW.salary

ORA-00927: 缺少等号

ORA-00927: missing equal sign
