先建一个简单的表,表里有 a、b 两个字段,并分别建上索引
CREATE TABLE `t` (
`id` int(11) NOT NULL,
`a` int(11) DEFAULT NULL,
`b` int(11) DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `a` (`a`),
KEY `b` (`b`)
) ENGINE=InnoDB;
存储过程脚本
delimiter ;;
create procedure idata()
begin
declare i int;
set i=1;
START TRANSACTION;
while(i<=100000)do
insert into t values(i, i, i);
set i=i+1;
end while;
commit;
end;;
delimiter ;
call idata();
