创建测试表：mysql> create table bigdata (id int,name char(2));创建存储过程：mysql> delimiter //mysql> create procedure rand_data(in num int)-> begin-> declare str char(62) default 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'; --总共62个字符。-> declare str2 char(2);-> declare i int default 0;-> while i<num do-> set str2=concat(substring(str,1+floor(rand()*61),1),substring(str,1+floor(rand()*61),1));-> set i=i+1;-> insert into bigdata values (floor(rand()*num),str2);-> end while;-> end;-> //Query OK, 0 rows affected (0.01 sec)mysql> delimiter ;插入一百万条数据：
mysql> call rand_data(1000000);
Query OK, 1 row affected (1 hour 11 min 34.95 sec)
