C++ 如何绑定SOCI查询的输出？

以下代码：生成错误消息，如下所示：

bool-UACmUsers:：GetUser（int-userid）{
会话sql（dbU:：Connection（））；
sql您的字符串不是标准字符串。wxString可能在SOCI中不支持转换

要么进行转换，要么扩展类型转换。可能不是最有效的，但有效：

namespace soci {
    template <> struct type_conversion<wxString> {
        typedef std::string base_type;

        static void from_base(base_type const& s, indicator ind, wxString& ws) {
            if (ind == i_null)
                ws.clear();
            else
                ws = s;
        }

        static void to_base(const wxString& ws, base_type& s, indicator& ind) {
            s = ws.ToStdString();
            ind = i_ok;
        }
    };
} // namespace soci

或在后续运行中：

在示例中，当insert语句抛出时，似乎存在内存泄漏。我想这需要向上游报告

在数据库中存储密码之前，请三思。正确的安全经验规则：


永远不要存储密码。句号
总是存储散列
不要使用快速哈希或非加密强哈希（不要使用MD5或SHA废话）
