1,客户端需要安装mysql-client包,安装完后有我们需要的库文件;
2,然后安装mysql-dev包,安装完后有我们需要的mysql.h文件;
3,作为客户端只需要安装这两个包就可以了:
以下是简单的测试代码:
#include
#include
int main()
{
/*declare structures and variables */
MYSQL mysql;
MYSQL_RES *result;
MYSQL_ROW row;
//initialize MYSQL structure
mysql_init(&mysql);
//connect to database
// mysql_real_connect(&mysql,"localhost","root","nriet","test",0,NULL,0);
mysql_real_connect(&mysql,"192.168.13.27","root","nriet","nriet",0,NULL,0);
//execute query
mysql_query(&mysql,"select * from test");
//get result set
result=mysql_store_result(&mysql);
//process result set
while((row=mysql_fetch_row(result)))
{
fprintf(stdout,"%s - %s\n",row[0],row[1]);
}
//mysql_query(&mysql,"insert into test values(3,'a')");
//clean up
mysql_free_result(result);
mysql_close(&mysql);
}
4,在“GCC C++ Linker”下的“Libraries”:
libraries(-l):mysqlclient
Libraries search path(-L):/usr/lib/mysql
然后 就可以 大功告成了 !!

The history and evolution of C# and C are unique, and the future prospects are also different. 1.C was invented by BjarneStroustrup in 1983 to introduce object-oriented programming into the C language. Its evolution process includes multiple standardizations, such as C 11 introducing auto keywords and lambda expressions, C 20 introducing concepts and coroutines, and will focus on performance and system-level programming in the future. 2.C# was released by Microsoft in 2000. Combining the advantages of C and Java, its evolution focuses on simplicity and productivity. For example, C#2.0 introduced generics and C#5.0 introduced asynchronous programming, which will focus on developers' productivity and cloud computing in the future.

Golang is better than C in concurrency, while C is better than Golang in raw speed. 1) Golang achieves efficient concurrency through goroutine and channel, which is suitable for handling a large number of concurrent tasks. 2)C Through compiler optimization and standard library, it provides high performance close to hardware, suitable for applications that require extreme optimization.

Oracle is not only a database company, but also a leader in cloud computing and ERP systems. 1. Oracle provides comprehensive solutions from database to cloud services and ERP systems. 2. OracleCloud challenges AWS and Azure, providing IaaS, PaaS and SaaS services. 3. Oracle's ERP systems such as E-BusinessSuite and FusionApplications help enterprises optimize operations.

Writing code in Visual Studio Code (VSCode) is simple and easy to use. Just install VSCode, create a project, select a language, create a file, write code, save and run it. The advantages of VSCode include cross-platform, free and open source, powerful features, rich extensions, and lightweight and fast.

Golang and C each have their own advantages in performance competitions: 1) Golang is suitable for high concurrency and rapid development, and 2) C provides higher performance and fine-grained control. The selection should be based on project requirements and team technology stack.

The performance differences between Golang and C are mainly reflected in memory management, compilation optimization and runtime efficiency. 1) Golang's garbage collection mechanism is convenient but may affect performance, 2) C's manual memory management and compiler optimization are more efficient in recursive computing.

Python is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.

Visual Studio Code (VSCode) is a cross-platform, open source and free code editor developed by Microsoft. It is known for its lightweight, scalability and support for a wide range of programming languages. To install VSCode, please visit the official website to download and run the installer. When using VSCode, you can create new projects, edit code, debug code, navigate projects, expand VSCode, and manage settings. VSCode is available for Windows, macOS, and Linux, supports multiple programming languages and provides various extensions through Marketplace. Its advantages include lightweight, scalability, extensive language support, rich features and version
