Example
以下是一个示例，我们创建了一个简单的过程，从表格 ‘student_info’ 中获取所有记录，这些记录具有以下数据 −
mysql> select * from student_info;
+-----+---------+------------+------------+
| id | Name | Address | Subject |
+-----+---------+------------+------------+
| 100 | Aarav | Delhi | Computers |
| 101 | YashPal | Amritsar | History |
| 105 | Gaurav | Jaipur | Literature |
| 110 | Rahul | Chandigarh | History |
+------+--------+------------+------------+
4 rows in set (0.00 sec)
登录后复制
现在，通过以下查询，我们创建了名为allrecords()的存储过程
mysql> Delimiter //
mysql> Create Procedure allrecords()
-> BEGIN
-> Select * from Student_info;
-> END//
Query OK, 0 rows affected (0.02 sec)
mysql> DELIMITER ;
