请大牛们给点 sql语句重用的办法?

Jun 23, 2016 pm 02:05 PM

现在是我有几条非常长的sql语句,需要在不同地方分别应用,所以我想把它们分别写成存储过程来公用,也方便调试。
存储过程已经写好了,但是我用php调用的时候,每调用一个存储过程都要做一次新的数据连接,感觉太麻烦,太耗资源。
请问有没有更好的sql语句重用的方法,或是怎么处理一个php页面调用存储过程,而不关闭连接。谢谢!

现在实现方法如下:

$pdobakpro1 = new PDO('mysql:host=localhost;dbname=test','root','123456');
$pdobakpro2 = new PDO('mysql:host=localhost;dbname=test','root','123456');

    $sql1 = "call pro_1()";//一个存储过程一个数据库连接

    $stmt1 = $pdobakpro1->query($sql1);

    var_dump($stmt1);

$sql2 = "call pro_2()";//调第二个存储过程需建一个新的数据库连接

    $stmt2 = $pdobakpro2->query($sql2);

    var_dump($stmt2);

你 $stmt1 = $pdobakpro1->query($sql1); 后
把 $stmt1 的内容读出来就可以了


$pdobakpro1 = new PDO('mysql:host=localhost;dbname=test','root','123456');
$pdobakpro2 = new PDO('mysql:host=localhost;dbname=test','root','123456');

$pdobakpro1 = new PDO('mysql:host=localhost;dbname=test','root','123456');
$pdobakpro2 = clone $pdobakpro1;
是一样的
并没有“太耗资源”一说


$pdobakpro1 = new PDO('mysql:host=localhost;dbname=test','root','123456');
$pdobakpro2 = new PDO('mysql:host=localhost;dbname=test','root','123456');

$pdobakpro1 = new PDO('mysql:……

谢谢,好吧,明白版本大人的意思了。
我只想知道大家在用PHP调用存储过程是不是都要这样,一个存储过程连一次数据库。还是我操作错误。

一个存储过程可以返回多个结果集
我不明白的是,你为什么要把不相干的存储过程放在一起执行,而不是处理完一个在执行下一个
如果两个存储过程的结果想干,那么为什么不放在一个里面执行

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
