I am new in QT in C++ 98. I have made this project using netbeans

Netbeans C++ QT Application [image]


In this project I have made new QT From

QT Form [image]

I am trying to import SQL but it failed.Using this code in "newFrom.cpp"

C++
#include <stdlib.h>
    #include <iostream>
    #include <mysql_driver.h>
    #include <mysql_connection.h>
    #include <exception.h>
    #include <sstream>
    #include <stdexcept>
    
    #include <cppconn/driver.h>
    #include <<cppconn/exception.h>
    #include <cppconn/connection.h>
    #include <cppconn/resultset.h>
    #include <cppconn/statement.h>
    #include <cppconn/prepared_statement.h>
    
    using namespace std;
    using namespace sql;     // <---- add here

I am getting this error

Your problem is that all those header files cannot be found. It may be that they are in a subdirectory of your project, in which case you need to change the angle brackets to double quotes, thus:
C++
#include "mysql_driver.h"
#include "mysql_connection.h"

#include "cppconn/driver.h"
#include "cppconn/exception.h"
#include "cppconn/connection.h"
#include "cppconn/resultset.h"
#include "cppconn/statement.h"
#include "cppconn/prepared_statement.h"

If that is not the case, and they are stored somewhere elxe then you need to add their location to your set of include directory names.

Addng "" in all includes still give error.

I can not find location like cppconn in include.

Sorry, but it's your system so you are the only person who knows where these files are located.
