Insert the volume of data stored procedure

DELIMITER $$

DROP PROCEDURE IF EXISTS `test`.`sp_insert_batch`$$

CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_insert_batch`(IN number int(11))

BEGIN

declare i int(11);

set i = 1;

-- such as 1-2000,2000-4000,....

WHILE i '' then

set @sqltext=concat('insert into song (name,datetime,rank) values',@sqltext);

prepare stmt from @sqltext;

execute stmt;

DEALLOCATE PREPARE stmt;

set @sqltext='';

end if;

END$$

DELIMITER ;

附表结构。
