mysql循环添加数据

已经测试，创建并运行下面的存储过程可以循环添加数据：

create procedure dowhile()

begin

declare i int default 0

start transaction

while i<50 do

insert into users(userId,userName,userPwd) values(null,concat('s00',i),123456)

set i=i+1

end while

commit

end

delimiter

DROP PROCEDURE IF EXISTS excute_job_v340

create procedure excute_job_v340()

begin 

        declare rdevid int//声明参数

        declare rech_id int

        declare slot int

        declare new_rech_id int

        declare new_price DOUBLE//声明参数

        declare done INT DEFAULT FALSE////声明结束标识参数

    --  声明游标

        DECLARE rdevrech_id CURSOR FOR

                select r.id as rdevid,r.rechargeconfig_id as rech_id,r.slot_no as slot from b_device_tbl dev

                where dev.dev_typedef_id =7 and dev.masterid is not NULL  and r.rechargeconfig_type=4 and r.is_deleted=0 and                 r.slot_no is not  NULL

        OPEN  rdevrech_id

                FETCH  NEXT from rdevrech_id INTO rdevid,rech_id,slot

                IF done THEN

                        LEAVE read_loop

                END IF// 结束判断
