string agivenpassword;

if agivenpassword is all numbers like "123" it fails with a cannot convert data SOCI exception.

if it has letters, it works fine.

*m_pSQLConnection << "SELECT 'accountID', 'banned', 'accessLevel' FROM account_data WHERE username = :username AND password = MD5(MD5(salt)|| MD5(:password))",
   into(aid), into(banned), into(accesslvl), use(username), use(agivenpassword);
