Error Code: 1305. FUNCTION student.rand_string does not exist，randstring

1、錯誤描述

13:52:42call new_procedureError Code: 1305. FUNCTION student.rand_string does not exist0.000 sec

2、錯誤原因

CREATE DEFINER=`root`@`localhost` PROCEDURE `new_procedure`()BEGIN  set @a=101;  while @a<2000 do  set @b = rand_string(10);  set @c=1;  insert into example1 values(@a,@b,@c);  set @a=@a+1;  if(@a%2=0)     then     set @c=0;     end if;  end while;END

    在`new_procedure`預存程序中，需要調用rand_string預存程序，但是rand_string預存程序沒有寫

3、解決辦法

    建立一個rand_string預存程序，用於產生隨機字串
