MySQL存储过程循环插入数据_MySQL

bitsCN.com 测试机器时经常要测试inset 和alert 的绝对值,所以写了个存储过程来完成.


DROP PROCEDURE IF EXISTS proc_buildata;
tudou@Gyyx
CREATE PROCEDURE proc_buildata(IN loop_times INT)
BEGIN
DECLARE var INT DEFAULT 0;

PREPARE MSQL FROM &＃39;CREATE TABLE IF NOT EXISTS `employee` (`id` int(10) unsigned NOT NULL AUTO_INCREMENT,`employeeid` int(10) unsigned NOT NULL COMMENT &＃39;&＃39;0&＃39;&＃39;,`employeename` varchar(64) NOT NULL DEFAULT &＃39;&＃39;&＃39;&＃39;,PRIMARY KEY (`id`)) ENGINE=InnoDB&＃39;;
EXECUTE MSQL;

WHILE varSET var=var+1;
INSERT INTO employee (employeeid,employeename) VALUES (var,CONCAT(&＃39;test&＃39;,var));

END WHILE;
END

CALL proc_buildata(2000000);


SELECT COUNT(1) FROM employee;
