这是我第一次使用触发器我不知道出了什么问题。甚至在插入时也没有显示任何错误。数据插入mas_stock工作正常但不触发??

Answer 1

必须添加

：

 CREATE TRIGGER (TRIGGER_NAME) before delete on (NAME_TABLE)
FOR EACH ROW EXECUTE PROCEDURE insert_data_into_stock_ledger_for_opstock();

Answer 2

CREATE TRIGGER insert_opening_stock 插入mas_stock后对于每一行执行程序insert_data_into_stock_ledger_for_opstock（）;

这个触发器无法插入触发器表有什么问题？
