MySQL 怎样创建一个存储过程来向MySQL的表中插入值？

我们可以创建一个带有IN运算符的存储过程向MySQL表中插入值。为了让大家理解，我们以一个名为“student_info”的表为例，该表包含以下数据 –

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)

现在，通过创建名为“insert_studentinfo”的存储过程，我们可以向“student_info”表中插入值 –

mysql> DELIMITER //;
mysql> Create PROCEDURE insert_studentinfo(IN p_id int, IN p_name varchar(20),IN p_Address Varchar(20), IN p_subject Varchar(20))
    -> BEGIN
    -> insert into student_info(id, name, address, subject) values (p_id, p_name,p_address, p_subject);
    -> END //
Query OK, 0 rows affected (0.09 sec)

现在，按照以下方式调用该过程以向表中插入我们想要的值 –

mysql> CALL insert_studentinfo(125,'Raman','Bangalore','Computers')//
Query OK, 1 row affected (0.78 sec)

mysql> DELIMITER ; //

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    |
| 125 | Raman   | Bangalore  | Computers  |
+------+---------+------------+-----------+
5 rows in set (0.00 sec)

上面的结果集表明值已插入表中。
