mysql>LOAD DATA INFILE ‘/tmp/student1.txt‘
INTO TABLE school.student1
FIELDS TERMINATED BY ‘,‘
OPTIONALLY ENCLOSED BY‘ ‘‘ ‘
LINES TERMINATED BY ‘ \N‘;
delimiter $$ #声明存储过程的结束符号为$$
create procedure auto_insert2()

declare i int default 60137;
while(i<300000)do
insert into s1 values(i,‘egon‘,‘male‘,concat(‘egon‘,i,‘@oldboy‘));
