c++ - MySQL C++ 连接器更新

Question

我在使用 MySQL C++ 连接器时遇到问题...我的问题是我有一个查询:UPDATE characters SET name = 'myNameIs' WHERE characregistra = 'MyguidIs' characters 就是表，name 列，characregistra 也是。当我在 characregistra 列中找到值“MyguisIs”时，我尝试将 myNameIs 值放入名称中。它可以工作，但如果没有 try{]catch{]，它就会崩溃。我试图用 sql::SQLException 来获取错误，但没办法，没有任何打印... 提前致谢。

编辑:忘了放代码:

void renameCharac(std::string guid, std::string pseudo)
{
    try{
        sql::Statement *declaration;
        declaration = connection->createStatement(); // Connection is declared
        declaration->executeQuery("UPDATE characters SET name = '" + pseudo + "' WHERE characregistra = '" + guid + "'");
        delete declaration;
    }
    catch (sql::SQLException e)
    {
        std::cout << e.what();
    }
}

Answer 1

最后我这样做了:

void renameCharac(std::string guid, std::string pseudo)
{
        sql::Statement *declaration;
        declaration = connection->createStatement();
        declaration->executeUpdate("UPDATE characters SET name = '" + pseudoChoisi + "' WHERE characregistra = '" + guid + "'");
        delete declaration;
}

有效。
