Question

我想在表上使用触发器，每次插入，更新，删除行时都会触发该触发器。我写了类似这样的内容：遗憾的是，我调用的函数不起作用，它给出了java.sql.SQLSyntaxErrorException :ora-04098 : trigger Compiere3.test01 is invalid and failed re-validation.

CREATE OR REPLACE TRIGGER test001
   AFTER INSERT OR UPDATE OR DELETE
   ON m_transaction
   FOR EACH ROW
DECLARE
   Availableqty   NUMBER;
BEGIN
   Availableqty := BOMQTYAVAILABLE (:old.m_product_id, 1000000, 1000000);

   INSERT INTO MonitorTable (m_transaction_id, m_product_id, Availableqty)
        VALUES (OLD.m_transaction_id, OLD.m_product_id, Availableqty);
END;

Answer 1

最后我找到了解决方案，正确的语法如下：

CREATE OR REPLACE TRIGGER test001
   AFTER INSERT OR UPDATE OR DELETE
   ON m_transaction
   FOR EACH ROW
DECLARE
   Availableiqty   NUMBER;
BEGIN
   Availableiqty := BOMQTYAVAILABLE (:new.m_product_id, 1000000, 1000000);

   INSERT INTO MonitorTable (m_transaction_id, m_product_id, Availableqty)
        VALUES (:new.m_transaction_id, :new.m_product_id, Availableiqty);
END;

Answer 2

在你的列名子句中，也许Availableqty应该是m_availableqty？基于您明显的命名约定。它期待一个列名并获得一个变量。

无法调用并插入函数在触发器内返回的值，是否有任何我缺少的东西？
