错误插入


delimiter $$     //以delimiter来标记用$表示存储过程结束
create procedure pre()		//创建pre()存储方法
begin
declare i int;		//定义i变量
set i=6001;
while i<6021 do		//对i的值配置
insert into assisted_material (id,name,edition_id,stages_id,grade_id,subject_id,volume,type,status,price,chapter_id,publisher)
	values(i,"老师课本+",111,2,2,1,"3","material","enabled","50",3,"人民出版社"); 
set i=i+1;		//自增循环
end while;
end 
$$		//存储过程结束
call pre();		//调用pre()存储方法

正确插入

delimiter $$
create procedure pr()
begin
declare i int;
set i=5000;
while i<6000 do
	insert into assisted_material (id,name,edition_id,stages_id,grade_id,subject_id,volume,type,status,price,chapter_id,publisher)
	values(i,"老师课本+",111,2,2,1,"3","material","enabled","50",3,"人民出版社"); 
set i=i+1;
end while;
end 
$$
call insertdata();
