Ubuntu下的c++连接数据库
在Ubuntu环境下使用C++连接数据库,确保你的源码开发环境准备工作充分。首先,源码安装必要的源码nplayer输出dts源码开发工具和库。
执行命令
shell
sudo apt-get install g++ glibc glibc-source build-essential libmysql++-dev libmysqlclient libmysqlclient-dev
这些命令将帮助你获取并安装GCC、源码GLIBC、源码uboot源码下载相关源码及MySQL客户端库等。源码
接下来,源码准备一个C++示例程序来验证连接。源码以下是源码一个基本的示例代码,展示了如何与MySQL数据库建立连接,源码执行查询并检索数据。源码
cpp
#include
#include // MySQL相关库头文件
int main() {
MYSQL *mysql;
MYSQL_RES *res;
MYSQL_ROW row;
char query[];
int t,源码okhttp源码解析 r;
mysql = mysql_init(NULL);
if (!mysql_real_connect(mysql, "test", "root", "", "test", 0, NULL, 0)) {
std::cout << "Error connecting to database: " << mysql_error(mysql) << std::endl;
} else {
std::cout << "Connected.\n";
}
std::sprintf(query, "select * from first");
t = mysql_query(mysql, query);
if (t) {
std::cout << "Error making query: " << mysql_error(mysql) << std::endl;
} else {
std::cout << "Query made.\n";
}
res = mysql_use_result(mysql);
for (r = 0; r < row = mysql_fetch_row(res); if (row < 0) break;) {
for (t = 0; t < row[t];) {
std::cout << row[t] << "\n";
}
}
mysql_close(mysql);
return 0;
}
最后,编译程序并链接MySQL库。源码
shell
gcc test.cpp -lmysqlclient
注意,源码有时可能需要手动指定头文件路径。源码地带确保所有文件都已正确编译并链接。
此指南提供了在Ubuntu系统中设置C++环境及连接MySQL数据库的基本步骤。根据实际情况调整代码和配置,android记事本源码以满足具体需求。
