贴出D:\jreate_fun_getID.sql
看上去应该是有 create procedure 语句，但未使用 delimiter //

drop function if EXISTS getID;#删除方法

要怎么写 啊
delimiter //
create FUNCTION getID()RETURNS VARCHAR(26)
BEGIN
DECLARE char_now VARCHAR(20);
DECLARE char_round varchar(6);
DECLARE char_return varchar(26);
DECLARE count TINYINT ;
set count=1;
while count=1
do
select NOW()+'' into char_now from dual;
select round(round(rand(),6)*1000000) into char_round from dual;
set char_return=CONCAT(char_now,char_round);
if LENGTH(char_return)=20 then
select count('x') into count from pk_tbl where cloum=char_return;
#判断是否存在
if count=0 THEN
insert into pk_tbl (cloum) values(char_return);
end if;
end if;
end while;
return char_return;
end;
//
delimiter ;

按你说的 我成功了，在cmd里面执行 可以，
还有两个问题帮忙解答下：
1，怎么些批次执行脚本
2 我在可视花窗口执行报错下面的：
mysql> \. D:\jreate_fun_getID.sql;
1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '\. D:\jreate_fun_getID.sql' at line 1
mysql>
把所有的脚本都改正。
修改脚本，在WINDOWS的DOS窗口下
mysql -u -p<D:\jreate_fun_getID.sql;
