php 生成一个sql文件 导入~
<code>INSERT INTO `table` ( `field1`, `field2` ) VALUES ( 1,1 ), ( 2,2 ) .... ( 5000,5000 ); </code>
自己偶然间发现了一个纯 SQL 的办法, 嘎嘎!
BENCHMARK(loop_count,expression)
试试存储过程 比PHP要快多了
declare i int default 0;
while i
insert into users(value) values(RAND());
set i = i + 1;
end while;
一句SQL不是就搞这了
貌似不行把，之前问过专业dba
