php调用mysql存储过程实例分析
这篇文章主要介绍了php调用mysql存储过程,综合各种常见实例分析了php调用mysql存储过程的各种常见操作与使用技巧,具有一定的参考借鉴价值,需要的朋友可以参考下
本文实例分析了mysqldata/mysql/20140716116128.html">php调用mysql存储过程的方法。分享给大家供大家参考。具体分析如下:
Mysql存储过程创建语法,代码如下:
CREATE PROCEDURE和CREATE FUNCTION :
复制代码 代码如下:
CREATE PROCEDURE sp_name ([proc_parameter[,...]])
[characteristic ...] routine_body
CREATE FUNCTION sp_name ([func_parameter[,...]])
RETURNS type
[characteristic ...] routine_body
proc_parameter:
[ IN | OUT | INOUT ] param_name type
func_parameter:
param_name type
type:
Any valid MySQL data type
characteristic:
LANGUAGE SQL
| [NOT] DETERMINISTIC
| { CONTAINS SQL | NO SQL | READS SQL DATA | MODIFIES SQL DATA }
| SQL SECURITY { DEFINER | INVOKER }
| COMMENT 'string'
routine_body:
Valid SQL procedure statement or statements
当我们看完以后,就可以开始写一些简单的存储过程了,首先建立存储过程, Create procedure(子程序)、Create function(函数),代码如下:
复制代码 代码如下:
Create procedure sp_Name ([proc_parameter ])
routine_body
这里的参数类型可以是 IN OUT INOUTT,意思和单词的意思是一样的,IN 表示是传进来的参数,OUT 是表示传出去的参数,INOUT 是表示传进来但最终传回的参数,代码如下:
复制代码 代码如下:
Create functionsp_Name ([func_parameter ])
Returns type
Routine_body
Returns type 指定了返回的类型,这里给定的类型与返回值的类型要是一样的,否则会报错,下面是一个简单的例子,代码如下:
复制代码 代码如下:
mysql> delimiter //
mysql> create procedure g
-> begin
-> select version() i
-> end
-> //
Query OK, 0 rows affected
mysql> call getversion(@a
-> //
Query OK, 0 rows affected
mysql> select @a;
-> //
+---------------------+
| @a |
+---------------------+
| 5.0.45-community-nt |
+---------------------+
1 row in set (0.05 sec)
一个获取当前mysql版本的存储过程.那么php怎么与mysql的存储过程相结合呢.以下来自百度知道,代码如下:
复制代码 代码如下:
Drop table if exists user;
Create table user(
Id int unsigned not null auto_increment,
Name varchar(20) not null,
Pwd char(32) not null,
Primary key(Id)
);
添加用户的存储过程,代码如下:
复制代码 代码如下:
Delimiter //
Create procedure insertuser(in username varchar(20),in userpwd varchar(32))
Begin
Insert into welefen.user(Name,Pwd) values (username,md5(userpwd));
End
//
验证用户的存储过程,代码如下:
复制代码 代码如下:
Delimiter //
Create procedure validateuser(in username varchar(20),out param1)
Begin
Select Pwd into param1 from welefen.user where Name=username;
End
//
修改密码的存储过程,代码如下:
复制代码 代码如下:
Delimiter //
Create procedure modifyPwd(in username varchar(20),in userpwd varchar(32))
Begin
Update welefen.user set Pwd=md5(userpwd) where Name=username;
End
//
删除用户的存储过程,代码如下:
复制代码 代码如下:
Delimiter //
Create procedure deleteuser(in username varchar(20))
Begin
delete from welefen.user where Name=username;
End
//
在客户端,我们给出如下的程序,代码如下:
复制代码 代码如下:

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen
