Prepared Statement continuously returning null set (1 reply)

I'll admit I'm new at this (clearly, this being my second post in several hours). The basic setup is such: I'm currently using two C++ applications I wrote to connect to eachother. One machine serves as a log-in server, and is running MySQL with a users table as a background process. The other sends login data (handle and password) via WinSock2. The server received the info and queries the database. However, every time I query it throws an exception, and I have no idea how to fix it.

Running the same query using the MySQL command prompt yields a 1x1 table with the user's password.

Here is my code:

cout<<"Connecting to SQL database"<<endl;
m_SQLDriver = get_driver_instance();
m_SQLCon = m_SQLDriver->connect("tcp://127.0.0.1:3306/nebulous", "root", "**pass**");
m_SQLCon->setAutoCommit(false);

...

try
{
cout<<"Querying SQL Database"<<endl;

m_SQLPrepStatement = m_SQLCon->prepareStatement("SELECT password FROM users WHERE handle = (?)");
m_SQLPrepStatement->setString(1, handle);
m_SQLResultSet = m_SQLPrepStatement->executeQuery();

std::string Pass = password;

/*if(m_SQLResultSet->wasNull())
{
cout<<"Query returned null result."<<endl;
respond = LOGIN_RESULT_USERNAMEBAD;
}*/
if(Pass == m_SQLResultSet->getString("password"))
{
cout<<"Password match. Login successful."<<endl;
respond = LOGIN_RESULT_ACCEPTED;
}
else
{
cout<<"Password mismatch. Login FAILED."<<endl;
respond = LOGIN_RESULT_PASSBAD;
}
}
catch(sql::SQLException &e)
{
cout<<"ServerHandler::ReadPackets() Caught MySQL error on log-in attempt"<<endl;
cout<<"ERROR: "<<e.what()<<endl;
cout<<"/t(MySQL error code: "<<e.getErrorCode()<<endl;

respond = LOGIN_RESULT_MYSQLERROR;
}

If anyone has run into this before, or knows what I'm doing wrong (I'm sure there's plenty of it), I'd appreciate the help.
