【讨论】大家说说php+mysql使用存储过程的优缺点

May 10, 2018 pm 04:09 PM

一直在项目中都没用过  
看过一些开源系统也没用过存储过程  
都是sql 一条条执行  
在php项目中 使用存储过程需要吗   
使用存储过程应该可以提高速度 减轻web服务器压力  
但同时增加了数据库服务器负荷 个人理解  
这方面比较有经验的同学说说看   
一起讨论下吧。

回复讨论(解决方案)

基本上涉及较小的数据库操作应该没必要吧   
频繁较复杂的使用应该可以明显提高效率把

没有人对这个感兴趣-。-

话说用处还真是不大,,既然有这个功能,那就用用吧,唯一的解释就是避免重复写sql语句。

-。- 怎么用处不大了  
在一些方面用处大着呢 安全方面   
还有它是编译好的  不用每次解析 编译  
就是会增加数据库负荷

还是谢谢说了自己看法。  

路过的大哥小哥 前辈专家等等  
说说看法吧,其实我想听比较专业的分析  
谢谢啦

有点伤性能!

有点伤性能!  
是提高性能吧-。-

看过一些开源系统也没用过存储过程,都是sql 一条条执行  
 
 不是所有数据库都支持存储过程的,比如 mysql4 就不支持  
 而且不同的数据库对于存储过程的语法也是有差异的  
    
在php项目中 使用存储过程需要吗    
 
 存储过程可以极大的提高算法的效率,如果可能的话,那就用吧  
 
使用存储过程应该可以提高速度 减轻web服务器压力  
 
 这是必然的  
 
但同时增加了数据库服务器负荷 个人理解  
 
 这个理解是错误的,那些 一条条执行的sql 就不需要数据库服务器的开销吗?  

所做的项目一直在用存储过程,  
 
相对来说,维护比较方便

在mysql里没用过存储过程。

有了memcache和静态页面,存储过程就成了鸡肋,  
 
储存过程不是不好, 就是修改麻烦, 特别动态脚本, 改一下又要导入数据库, 倒来倒去, 简直是倒蛋,  
 
否则, 现在人人都写储存过程, 不写sql查询语句了。

但同时增加了数……  
它们都必然有开销,但不一样 :  
功能上好比php的内置函数,和外置函数的区别,  
用法上好比编译语言和解释语言的区别。  
特别是敏捷开发时代, 储存过程为了提高性能,   
如果修改一下编译一次, 修改一下编译一次, 这些开销真是不知从何谈起。  
 谢谢楼上几位大哥的回答

我写的存储过程在phpmyadmin里无法导入,一定要执行mysql_query才能导入,我擦

是提高性能吧-。- 那你所有的操作,干脆写存储过程算啦。有利有弊!

一说存储过程,让我想起毕业时找实习单位,有这么一家公司,面试的主管还很漂亮。可她出的题就是写一个存储过程的登录模块。所以有一点抵触了。^_^.  
不过话说回来,高负载,高并发网站应该用不到,高并发一般都用主从、LVS、中间件、垂直分库、水平分表。  
流行的使用nosql,即使用非关系型数据库,关于这个一般大型网站都在用。推荐一个redis。

有利有弊 结合项目  
有些简单的没必要当然不必啦  
性能上还是会提高的

首先看你的项目数据库的操作是否复杂,开发人员对数据库编程是否深入  
存储过程本身是提高性能的,只是对于简单的项目有些大材小用  
还有,你用存储过程的优势能封装事务,当然也是以操作复杂为前提的

存储过程一方面提高了sql编译效率,另一方面还可以在这里处理复杂业务逻辑。  
你说的那些都是说在高负载,高并发条件下,如何解决性能的问题,却不能解决处理复杂业务逻辑的问题。  
对与redis,我花了一点时间学习过,想处理复杂业务逻辑,难!

存储过程是否可以提高跨服务器的性能?  
比如php和mysql分别布置在不同服务器上的时候,如果php一条一条的执行,会有很多次跨服务器的调用,网络时延比较大;但如果用存储过程,php调用一次就行了。

PHP calls AI intelligent voice assistant PHP voice interaction system construction PHP calls AI intelligent voice assistant PHP voice interaction system construction Jul 25, 2025 pm 08:45 PM

User voice input is captured and sent to the PHP backend through the MediaRecorder API of the front-end JavaScript; 2. PHP saves the audio as a temporary file and calls STTAPI (such as Google or Baidu voice recognition) to convert it into text; 3. PHP sends the text to an AI service (such as OpenAIGPT) to obtain intelligent reply; 4. PHP then calls TTSAPI (such as Baidu or Google voice synthesis) to convert the reply to a voice file; 5. PHP streams the voice file back to the front-end to play, completing interaction. The entire process is dominated by PHP to ensure seamless connection between all links.

How to use PHP to build social sharing functions PHP sharing interface integration practice How to use PHP to build social sharing functions PHP sharing interface integration practice Jul 25, 2025 pm 08:51 PM

The core method of building social sharing functions in PHP is to dynamically generate sharing links that meet the requirements of each platform. 1. First get the current page or specified URL and article information; 2. Use urlencode to encode the parameters; 3. Splice and generate sharing links according to the protocols of each platform; 4. Display links on the front end for users to click and share; 5. Dynamically generate OG tags on the page to optimize sharing content display; 6. Be sure to escape user input to prevent XSS attacks. This method does not require complex authentication, has low maintenance costs, and is suitable for most content sharing needs.

How to use PHP combined with AI to achieve text error correction PHP syntax detection and optimization How to use PHP combined with AI to achieve text error correction PHP syntax detection and optimization Jul 25, 2025 pm 08:57 PM

To realize text error correction and syntax optimization with AI, you need to follow the following steps: 1. Select a suitable AI model or API, such as Baidu, Tencent API or open source NLP library; 2. Call the API through PHP's curl or Guzzle and process the return results; 3. Display error correction information in the application and allow users to choose whether to adopt it; 4. Use php-l and PHP_CodeSniffer for syntax detection and code optimization; 5. Continuously collect feedback and update the model or rules to improve the effect. When choosing AIAPI, focus on evaluating accuracy, response speed, price and support for PHP. Code optimization should follow PSR specifications, use cache reasonably, avoid circular queries, review code regularly, and use X

PHP creates a blog comment system to monetize PHP comment review and anti-brush strategy PHP creates a blog comment system to monetize PHP comment review and anti-brush strategy Jul 25, 2025 pm 08:27 PM

1. Maximizing the commercial value of the comment system requires combining native advertising precise delivery, user paid value-added services (such as uploading pictures, top-up comments), influence incentive mechanism based on comment quality, and compliance anonymous data insight monetization; 2. The audit strategy should adopt a combination of pre-audit dynamic keyword filtering and user reporting mechanisms, supplemented by comment quality rating to achieve content hierarchical exposure; 3. Anti-brushing requires the construction of multi-layer defense: reCAPTCHAv3 sensorless verification, Honeypot honeypot field recognition robot, IP and timestamp frequency limit prevents watering, and content pattern recognition marks suspicious comments, and continuously iterate to deal with attacks.

PHP realizes commodity inventory management and monetization PHP inventory synchronization and alarm mechanism PHP realizes commodity inventory management and monetization PHP inventory synchronization and alarm mechanism Jul 25, 2025 pm 08:30 PM

PHP ensures inventory deduction atomicity through database transactions and FORUPDATE row locks to prevent high concurrent overselling; 2. Multi-platform inventory consistency depends on centralized management and event-driven synchronization, combining API/Webhook notifications and message queues to ensure reliable data transmission; 3. The alarm mechanism should set low inventory, zero/negative inventory, unsalable sales, replenishment cycles and abnormal fluctuations strategies in different scenarios, and select DingTalk, SMS or Email Responsible Persons according to the urgency, and the alarm information must be complete and clear to achieve business adaptation and rapid response.

How to use PHP to combine AI to generate image. PHP automatically generates art works How to use PHP to combine AI to generate image. PHP automatically generates art works Jul 25, 2025 pm 07:21 PM

PHP does not directly perform AI image processing, but integrates through APIs, because it is good at web development rather than computing-intensive tasks. API integration can achieve professional division of labor, reduce costs, and improve efficiency; 2. Integrating key technologies include using Guzzle or cURL to send HTTP requests, JSON data encoding and decoding, API key security authentication, asynchronous queue processing time-consuming tasks, robust error handling and retry mechanism, image storage and display; 3. Common challenges include API cost out of control, uncontrollable generation results, poor user experience, security risks and difficult data management. The response strategies are setting user quotas and caches, providing propt guidance and multi-picture selection, asynchronous notifications and progress prompts, key environment variable storage and content audit, and cloud storage.

PHP integrated AI intelligent picture recognition PHP visual content automatic labeling PHP integrated AI intelligent picture recognition PHP visual content automatic labeling Jul 25, 2025 pm 05:42 PM

The core idea of integrating AI visual understanding capabilities into PHP applications is to use the third-party AI visual service API, which is responsible for uploading images, sending requests, receiving and parsing JSON results, and storing tags into the database; 2. Automatic image tagging can significantly improve efficiency, enhance content searchability, optimize management and recommendation, and change visual content from "dead data" to "live data"; 3. Selecting AI services requires comprehensive judgments based on functional matching, accuracy, cost, ease of use, regional delay and data compliance, and it is recommended to start from general services such as Google CloudVision; 4. Common challenges include network timeout, key security, error processing, image format limitation, cost control, asynchronous processing requirements and AI recognition accuracy issues.
