使用C++打印从SQLite3数据库检索到的数据，方法与在命令行中相同

#include <iostream>
#include <sqlite3.h>

int main() {
    sqlite3* db;
    int rc = sqlite3_open("your_database.db", &db);
    if (rc) {
        std::cerr << "Cannot open database: " << sqlite3_errmsg(db) << std::endl;
        return rc;
    }

    const char* sql = "SELECT * FROM your_table;";
    rc = sqlite3_exec(db, sql, [](void* data, int argc, char** argv, char** azColName) -> int {
        for (int i = 0; i < argc; i++) {
            std::cout << azColName[i] << " = " << (argv[i] ? argv[i] : "NULL") << std::endl;
        }
        return 0;
    }, nullptr, nullptr);

    if (rc != SQLITE_OK) {
        std::cerr << "SQL error: " << sqlite3_errmsg(db) << std::endl;
    }

    sqlite3_close(db);
    return 0;
}
