Mysql创建一张表并且添加一万条数据

创建一张表并且给表添加一万条数据，就是为了测试慢查询，可以作为测试数据

1.创建一张表

CREATE TABLE user100w(
  id INT NOT NULL AUTO_INCREMENT,
  first_name VARCHAR(10) NOT NULL,
  last_name VARCHAR(10) NOT NULL,
  sex VARCHAR(5) NOT NULL,
  score INT NOT NULL,
  copy_id INT NOT NULL,
  PRIMARY KEY (`id`)
);

2.创建存储过程

DROP PROCEDURE IF EXISTS add_user;  
DELIMITER //
    create PROCEDURE add_user(in num INT)
    BEGIN
        DECLARE rowid INT DEFAULT 0;
        DECLARE firstname CHAR(1);
        DECLARE name1 CHAR(1);
        DECLARE name2 CHAR(1);
        DECLARE lastname VARCHAR(3) DEFAULT '';
        DECLARE sex CHAR(1);
        DECLARE score CHAR(2);
        WHILE rowid < num DO
        SET firstname = SUBSTRING('赵钱孙李周吴郑王林杨柳刘孙陈江阮侯邹高彭徐',FLOOR(1+21*RAND()),1); 
        SET name1 = SUBSTRING('一二三四五六七八九十甲乙丙丁静景京晶名明铭敏闵民军君俊骏天田甜兲恬益依成城诚立莉力黎励',ROUND(1+43*RAND()),1); 
        SET name2 = SUBSTRING('一二三四五六七八九十甲乙丙丁静景京晶名明铭敏闵民军君俊骏天田甜兲恬益依成城诚立莉力黎励',ROUND(1+43*RAND()),1); 
        SET sex=FLOOR(0 + (RAND() * 2));
        SET score= FLOOR(40 + (RAND() *60));
        SET rowid = rowid + 1;
        IF ROUND(RAND())=0 THEN 
        SET lastname =name1;
        END IF;
        IF ROUND(RAND())=1 THEN
        SET lastname = CONCAT(name1,name2);
        END IF;
        insert INTO user100w (first_name,last_name,sex,score,copy_id) VALUES (firstname,lastname,sex,score,rowid);  
        END WHILE;
    END //
DELIMITER ;

3.调用存储过程

call add_user(1000000);

4.结果
