MySQL数据库接口的VC实现与应用(3)_MySQL
摘要：MySQL数据库作为一种网络数据库性能十分出色，但其在应用软件中使用较少。本文将主要探讨MySQL提供的两种数据库接口 ――（ODBC API和C API）在VC中的应用，并且形成一个类用以封装C API数据库接口的功能。
关键词：MySQL；数据库接口；ODBC API；C API
4 MySQL性能测试
4.1 ODBC API
通过索引读取200万行：528秒
插入35万行： 750秒
4.2 C API
通过索引读取200万行：412秒
插入35万行：435秒
4.3 其它数据库（以MS_SQL为例，WINNT环境）
通过索引读取200万行：1634秒
插入35万行：4012秒
注：以上数据是多次测量的平均值，不可避免一定的误差，仅供参考。
5 结束语
MySQL作为一个免费的SQL数据库，虽然功能不够十分强大，且灵活性较差，但是，已经能够满足一般应用软件的要求，而且MySQL数据库的开发者也在力求使之更加完善。并且，由MySQL性能测试可以看出，它对数据的处理速度明显快于其它数据库服务器。因此，如果应用软件对数据库的性能要求较高，而同时对数据库操作的功能及灵活性的要求不是很高的话，并且前期投入资金较少时，MySQL数据库服务器不失为一个最佳的选择。

What are the internal interfaces of a computer motherboard? Recommended introduction to the internal interfaces of a computer motherboard
Mar 12, 2024 pm 04:34 PM
When we assemble the computer, although the installation process is simple, we often encounter problems in the wiring. Often, users mistakenly plug the power supply line of the CPU radiator into the SYS_FAN. Although the fan can rotate, it may not work when the computer is turned on. There will be an F1 error "CPUFanError", which also causes the CPU cooler to be unable to adjust the speed intelligently. Let's share the common knowledge about the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard. Popular science on the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard 1. CPU_FANCPU_FAN is a dedicated interface for the CPU radiator and works at 12V
Common programming paradigms and design patterns in Go language
Mar 04, 2024 pm 06:06 PM
As a modern and efficient programming language, Go language has rich programming paradigms and design patterns that can help developers write high-quality, maintainable code. This article will introduce common programming paradigms and design patterns in the Go language and provide specific code examples. 1. Object-oriented programming In the Go language, you can use structures and methods to implement object-oriented programming. By defining a structure and binding methods to the structure, the object-oriented features of data encapsulation and behavior binding can be achieved. packagemaini
Introduction to PHP interfaces and how to define them
Mar 23, 2024 am 09:00 AM
Introduction to PHP interface and how it is defined. PHP is an open source scripting language widely used in Web development. It is flexible, simple, and powerful. In PHP, an interface is a tool that defines common methods between multiple classes, achieving polymorphism and making code more flexible and reusable. This article will introduce the concept of PHP interfaces and how to define them, and provide specific code examples to demonstrate their usage. 1. PHP interface concept Interface plays an important role in object-oriented programming, defining the class application
Solution to NotImplementedError()
Mar 01, 2024 pm 03:10 PM
The reason for the error is in python. The reason why NotImplementedError() is thrown in Tornado may be because an abstract method or interface is not implemented. These methods or interfaces are declared in the parent class but not implemented in the child class. Subclasses need to implement these methods or interfaces to work properly. How to solve this problem is to implement the abstract method or interface declared by the parent class in the child class. If you are using a class to inherit from another class and you see this error, you should implement all the abstract methods declared in the parent class in the child class. If you are using an interface and you see this error, you should implement all methods declared in the interface in the class that implements the interface. If you are not sure which
Insight into Hongmeng system: actual function measurement and usage experience
Mar 23, 2024 am 10:45 AM
As a new operating system launched by Huawei, Hongmeng system has caused quite a stir in the industry. As a new attempt by Huawei after the US ban, Hongmeng system has high hopes and expectations. Recently, I was fortunate enough to get a Huawei mobile phone equipped with Hongmeng system. After a period of use and actual testing, I will share some functional testing and usage experience of Hongmeng system. First, let’s take a look at the interface and functions of Hongmeng system. The Hongmeng system adopts Huawei's own design style as a whole, which is simple, clear and smooth in operation. On the desktop, various
Inner class implementation of interfaces and abstract classes in Java
Apr 30, 2024 pm 02:03 PM
Java allows inner classes to be defined within interfaces and abstract classes, providing flexibility for code reuse and modularization. Inner classes in interfaces can implement specific functions, while inner classes in abstract classes can define general functions, and subclasses provide concrete implementations.
Java interfaces and abstract classes: revealing the inner connection between them
Mar 04, 2024 am 09:34 AM
Interface Interface defines abstract methods and constants in Java. The methods in the interface are not implemented, but are provided by the class that implements the interface. The interface defines a contract that requires the implementation class to provide specified method implementations. Declare the interface: publicinterfaceExampleInterface{voiddoSomething();intgetSomething();} Abstract class An abstract class is a class that cannot be instantiated. It contains a mixture of abstract and non-abstract methods. Similar to interfaces, abstract methods in abstract classes are implemented by subclasses. However, abstract classes can also contain concrete methods, which provide default implementations. Declare abstract class: publicabstractcl
Application of interfaces and abstract classes in design patterns in Java
May 01, 2024 pm 06:33 PM
Interfaces and abstract classes are used in design patterns for decoupling and extensibility. Interfaces define method signatures, abstract classes provide partial implementation, and subclasses must implement unimplemented methods. In the strategy pattern, the interface is used to define the algorithm, and the abstract class or concrete class provides the implementation, allowing dynamic switching of algorithms. In the observer pattern, interfaces are used to define observer behavior, and abstract or concrete classes are used to subscribe and publish notifications. In the adapter pattern, interfaces are used to adapt existing classes. Abstract classes or concrete classes can implement compatible interfaces, allowing interaction with original code.
