使用SqliteModernCpp进行SQLite更新查询的步骤如下: 引入SqliteModernCpp库:在项目中引入SqliteModernCpp库的头文件和链接库。 创建数据库连接:使用SqliteModernCpp提供的接口,创建一个数据库连接对象。 执行更新操作:使用连接对象的execute方法,传入SQL语句进行数据库的更新操作。例如,可以使
#include<sqlite_modern_cpp.h>structUser{longlong_id; std::optional<int> age; std::optional<string> name; std::optional<real> weight; };intmain() { User user; user.name="bob";//Same database as abovedatabasedb("dbfile.db");//Here, age and weight will be inserted as NULL in th...

然后,创建一个C++源文件,例如SQLiteExample.cpp,并添加以下代码: #include <iostream> #include <sqlite3.h> // 创建数据库连接 sqlite3* OpenDatabase(const char* dbFilePath) { sqlite3* db; // 打开数据库 if (sqlite3_open(dbFilePath, &db) != SQLITE_OK) { std::cerr << "Error opening da...
