MySQL 缓存表建触发器

BEGIN
		IF (select new.name NOT REGEXP (SELECT IF((select filterword from t_crawl_configuration where id=new.crawl_id)='','fzuir',(select filterword from t_crawl_configuration where id=new.crawl_id))) and new.price>=(select lowest_price from t_crawl_configuration where id=new.crawl_id))  then
						insert into t_product_data(crawl_url_id,pid,name,price,crawl_id) values(new.crawl_url_id,new.pid,new.name,new.price,new.crawl_id);
		end if;
END

插入表格过程中建立触发器

-- 触发器 同时插入有用数据
DROP TRIGGER IF EXISTS t_afterinsert_on_t_product;
CREATE TRIGGER t_afterinsert_on_t_product
AFTER INSERT ON t_product
FOR EACH ROW
