使用存储过程在mysql里创建大量测试数据

create table t1(id int primary key, a int, b int, index(a));
create table t2 like t1;
drop procedure idata;
delimiter ;;
create procedure idata()
begin
declare i int;
set i=1;
while(i<=1000)do
insert into t1 values(i, 1001-i, i);
set i=i+1;
end while;

set i=1;
while(i<=1000000)do
insert into t2 values(i, i, i);
set i=i+1;
end while;

end;;
delimiter ;
call idata();
