【mysql 存储过程】数据库从菜鸟走向大神系列3

主要内容：
1、建表
2、写存储过程
3、写事件（自动化）

mysql 建表语句：

CREATE TABLE `nld_op_data_statistics_day` (  `id` int(11) NOT NULL AUTO_INCREMENT,  `channel` varchar(16) NOT NULL COMMENT '渠道',  `count_date` varchar(16) NOT NULL COMMENT '日期',  `product` varchar(16) NOT NULL COMMENT '产品',  `apply_num` int(8) DEFAULT '0' COMMENT '当日申请数量',  `pass_num` int(8) DEFAULT '0' COMMENT '当日通过数量',  `pass_amount` decimal(20,2) DEFAULT '0.00' COMMENT '当日审批金额',  `loan_amount` decimal(20,2) DEFAULT '0.00' COMMENT '当日放款金额',  `loan_num` int(8) DEFAULT '0' COMMENT '当日放款数量',  `service_fail_num` int(8) DEFAULT '0' COMMENT '当日服务费代扣失败数量',  PRIMARY KEY (`id`),  KEY `Index 2` (`count_date`),  KEY `Index 3` (`product`)) ENGINE=InnoDB AUTO_INCREMENT=31 DEFAULT CHARSET=utf8 COMMENT='运营部农粒贷每日数据统计日报';

mysql 定义事件（调用存储过程，实现自动化插入数据到上面建立的表）

CREATE DEFINER=`ldf`@`%` EVENT `nld_op_data_statistics_day` ON SCHEDULE EVERY 1 DAY STARTS '2017-11-16 06:00:00' ON COMPLETION PRESERVE ENABLE DO CALL nld_op_data_statistics_day()
