Mysql中创建存储和调用存储过程(一)

创建存储过程

DELIMITER $$ --定义分割符
DROP PROCEDURE IF EXISTS getRecord $$
CREATE PROCEDURE getRecord (
IN in_id INTEGER,  --定义输入参数
OUT out_name VARCHAR(20), --输出参数
OUT out_age  INTEGER) ---输出参数
BEGIN
   SELECT name, age
   INTO out_name, out_age
   FROM Student where id = in_id;
END $$
DELIMITER ;

调用存储过程:

--调用存储过程
mysql> call getRecord(10,@name,@age);
Query OK, 1 row affected (0.51 sec)

--查询输出参数

mysql> select @name,@age;
+-----------+------+
| @name     | @age |
+-----------+------+
| 张胜男    |   22 |
+-----------+------+
1 row in set (0.02 sec)
