CREATE OR REPLACE TRIGGERS trigger

Answer 1

您有一些语法错误。它不是不是“触发器”。另外，提供有效的触发器名称。插入后缺少分号。

   CREATE OR REPLACE TRIGGER trigger_name
    AFTER INSERT ON table_001
    FOR EACH ROW
    BEGIN
        INSERT INTO table_002(new_Day_date) VALUES(SYSDATE);
    END;
    /

Answer 2

CREATE OR REPLACE TRIGGER trigger_name
AFTER INSERT ON table_001
FOR EACH ROW
BEGIN
    INSERT INTO table_002 VALUES(SYSDATE);
END;
