db2 insert trigger new 无效

Question

我已经定义了这个触发器：

--#SET TERMINATOR @
CREATE TRIGGER actualizarSaldoIngreso
BEFORE INSERT ON Ingreso
FOR EACH ROW MODE DB2SQL
BEGIN
    UPDATE Cuenta SET Saldo = Saldo + NEW.Cantidad WHERE IBAN = NEW.Cuenta_IBAN;
END@
--#SET TERMINATOR ;

但是db2 returns这个错误。有什么解决办法吗？

"NEW.CANTIDAD" is not valid in the context where it is used.

Answer 1

--#SET TERMINATOR @
CREATE TRIGGER actualizarSaldoIngreso
BEFORE INSERT ON Ingreso
REFERENCING NEW as N
FOR EACH ROW MODE DB2SQL
BEGIN
    UPDATE Cuenta SET Saldo = Saldo + N.Cantidad WHERE IBAN = N.Cuenta_IBAN;
END@
--#SET TERMINATOR ;
