mysql 创建存储过程报错

mysql5以上的版本都支持存储过程

我先创建了一张表：

create table tb_user
(
	user_id int primary key,
	user_name varchar(20) not null
);

默认情况下，创建存储过程会报错，如下：

mysql> create procedure pr_gen_users()
    -> begin
    ->  select * from tb_user;
ERROR 1064 (42000): 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 '' at
line 3
mysql> end;
ERROR 1064 (42000): 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 'end'
at line 1
mysql>

这是因为默认的分隔符是;，而select里已经有了一个分隔符。换一下分隔符就不会报错了

mysql> delimiter //
mysql> create procedure pr_gen_users()
    -> begin
    ->  select * from tb_user;
    -> end //
Query OK, 0 rows affected (0.00 sec)

这样就成功了
