void Player::SaveInventoryAndGoldToDB() { // Connect to database Database db; db.Connect(); // Prepare SQL statement std::string query = "UPDATE players SET inventory = '" + m_inventory + "', gold = " + std::to_string(m_gold) + " WHERE id = " + std::to_string(m_playerID); // Execute SQL statement db.ExecuteSQL(query); // Disconnect from database db.Disconnect(); }In this example, the Player class has a function called SaveInventoryAndGoldToDB that is used to save the player's inventory and gold to a database. The function starts by establishing a connection with the database using the Database class. Next, a SQL update statement is prepared using the player's inventory and gold values. The SQL statement updates the player's record in the database where the player ID matches the ID of the current player. Finally, the SQL statement is executed, and the database connection is closed. Package Library: This code example makes use of the Database class and SQL statements to access and manipulate a database. Therefore, it is likely that this code uses a third-party database library such as MySQL or SQLite.
