// windows 下编译记得修改报错的文件编码
封装mysql官方的cppconn c++接口的更高级封装(需要自行下载mysql cppconn)，使增删改查变得更加modern c++。
测试代码:
#include "sql_wrapper.h"
int main()
{
sql_wrapper sql_("tcp://127.0.0.1:3306", "root", "123456", "game");
bool ret_ = false;
// 创建
ret_ = sql_.create("create table test (id_ double, name_ varchar(64), password_ varchar(64)); ");
// 添加
ret_ = sql_.insert("insert into test (id_, name_, password_) values (0.1, '0.2', '0.3');"),
// 添加 —> 带参数
ret_ = sql_.insert("insert into test (id_, name_, password_) values (?, ?, ?);",
std::tuple<double, std::string, std::string>(0.11118, "0.2", "0.2"));
// 添加 —> 带参数
ret_ = sql_.insert("insert into test (id_, name_, password_) values (?, ?, ?);",
std::tuple<double, std::string, std::string>(0.8, "0.2", "0.2"));
// 删除
ret_ = sql_.remove("delete from test where id_ = '0.3';");
// 删除 —> 带参数
ret_ = sql_.remove("delete from test where id_ = ?;", std::tuple<std::string>("0.11118"));
// 更新
ret_ = sql_.update("update test set id_ = 0.1, name_ = 'test' where password_ = 0.1;"),
// 更新 —> 带参数
ret_ = sql_.update("update test set id_ = ?, name_ = ? where password_ = ?;",
std::tuple<double, std::string, std::string>(0.2, "humorly", "0.2"));
std::vector<std::tuple<double, std::string, std::string>> user_content_;
// 查询

std::tuple <>(),
