1. 批量建表
使用存储过程来实现
-- 1. 先删除存储过程
DROP PROCEDURE IF EXISTS `create_tables`;
-- 2. 结束符改为$
DELIMITER $
-- 3. 创建存储过程
CREATE PROCEDURE create_tables ()
BEGIN
DECLARE `@i` INT (11);
DECLARE `@createSql` VARCHAR (2560);
SET `@i` = 0;
WHILE `@i` < 100 DO
-- 创建表
SET @createSql = CONCAT(
"CREATE TABLE IF NOT EXISTS guess_record_", `@i`,
"(
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`userid` int(12) unsigned NOT NULL COMMENT '用户ID',
`issue` int(10) unsigned NOT NULL COMMENT '期号',
`options_id` int(10) unsigned NOT NULL COMMENT '选项ID',
`guess_time` int(10) unsigned NOT NULL COMMENT '答题时间',
`is_stat` tinyint(4) NOT NULL COMMENT '是否统计过',
PRIMARY KEY (`id`),
KEY `issue` (`issue`) USING BTREE,
KEY `userid` (`userid`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
"
);
PREPARE stmt FROM @createSql;
EXECUTE stmt;
SET `@i` = `@i` + 1;
END WHILE;
END $
-- 4. 结束符改为;
DELIMITER ;
-- 5. 执行存储过程
CALL `create_tables`();
-- 6. 删除存储过程
DROP PROCEDURE IF EXISTS `create_tables`;
2. 批量插入数据
DELIMITER $
create procedure batchInsert(in args int)
begin
declare i int default 1;
declare `@createSql` varchar(2560);
while i <= args do
set @createSql = CONCAT(
'insert into t_mysql_info (id, table_name) value(', i, ', "t_message_info_', i-1, '");'
);
prepare stmt from @createSql;
execute stmt;
set i = i+1;
end while;
end
$
DELIMITER ;
call batchInsert(100);
