How to set new date entries to current date?
提问by indolent
I am trying to create a trigger. It is supposed to update any new date entry to sysdate. So far, I have the following code. However, I get "invalid table name" and "SQL statement ignored" errors.
我正在尝试创建触发器。它应该将任何新的日期条目更新为 sysdate。到目前为止，我有以下代码。但是，我收到“无效的表名”和“忽略 SQL 语句”错误。
CREATE OR REPLACE TRIGGER new_orders
AFTER INSERT ON orders
FOR EACH ROW
BEGIN
IF INSERTING THEN
UPDATE
SET order_date := SYSDATE;
END IF;
END;
