通过存储过程来添加数据:

<code class="hljs vbnet">drop procedure if exists t1;
create procedure t1()
begin
    DECLARE i INT DEFAULT 0;
    DECLARE j INT DEFAULT 0;
    WHILE (i <= 15000000) DO
        INSERT INTO `test` (`code`, `name`) VALUES
        (&#39;sdfasdfas&#39;,&#39;aaa&#39;);
        SET i = i + 1;      
        if mod(i,1000)=0 then commit;
        end if;    
    END WHILE;
end;

/*调用存储过程*/
call t1();</code>

重要:在执行插入前,先改掉mysql 存储模式 !!不然插入速度很慢!!

<code class="hljs sql">ALTER TABLE test ENGINE = MYISAM;</code>

默认 值为InnoDB,如果还需要用这个,可在插入结束后改回来。
