MySQL 存儲過程循環插入數據

測試機器時經常要測試inset 和alert 的絕對值,所以寫了個存儲過程來完成.
 

DROP PROCEDURE IF EXISTS proc_buildata;

CREATE PROCEDURE proc_buildata(IN loop_times INT) 
BEGIN 
DECLARE var INT DEFAULT 0; 
 
PREPARE MSQL FROM 'CREATE TABLE IF NOT EXISTS `employee` (`id` int(10) unsigned NOT NULL AUTO_INCREMENT,`employeeid` int(10) unsigned NOT NULL COMMENT ''0'',`employeename` varchar(64) NOT NULL DEFAULT '''',PRIMARY KEY (`id`)) ENGINE=InnoDB';   
EXECUTE MSQL; 
 
WHILE var<loop_times DO 
SET var=var+1; 
INSERT INTO employee (employeeid,employeename) VALUES (var,CONCAT('test',var)); 
 
END WHILE; 
END 
 
CALL proc_buildata(2000000); 
 
 
SELECT COUNT(1) FROM employee;
