SQL之使用存储过程循环插入数据
1、已经创建了任务日志表
CREATE TABLE `t_task_log` (`id` bigint NOT NULL AUTO_INCREMENT,`task_id` bigint NOT NULL COMMENT '任务ID',`read_time` bigint NOT NULL COMMENT '单位秒，读取耗时',`write_time` bigint NOT NULL COMMENT '单位秒，写入耗时',`read_size` bigint NOT NULL COMMENT '读取记录数，单位条',`write_size` bigint NOT NULL COMMENT '写入记录数，单位条',`status` int NOT NULL COMMENT '0表示执行中，1表示执行失败，2表示执行成功',`created_by` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NOT NULL,`created_datetime` datetime NOT NULL,`last_updated_by` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NOT NULL,`last_updated_datetime` datetime NOT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=485521 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin;2、创建存储过程
DROP PROCEDURE loopAddLog;CREATE PROCEDURE loopAddLog()
begin
declare i int;
set i = 1;
repeatINSERT INTO hmblogs.t_task_log(task_id, read_time, write_time, read_size, write_size, status, created_by, created_datetime, last_updated_by, last_updated_datetime)VALUES(i, 10, 10, 100000, 100000, i%3, 'admin', now(), 'admin', now());set i = i + 1;
until i >= 100000000
end repeat;end3、执行存储过程
call loopAddLog();已经在插入数据了
