Chapter 1. Get in contact with your SQL Server


Example 1-1. Get in contact with your SQL Server

   1 #include <hk_classes.h>
   2 #include <iostream>
   3 int main()
   4 {
   5  hk_drivermanager* mydrivermanager = new hk_drivermanager();
   6  if (mydrivermanager==NULL) {cout <<"error creating mydrivermanager"<<endl;exit(1);}
   7  hk_connection* myconnection = mydrivermanager->new_connection();
   8  if (myconnection==NULL) {cout <<"error creating myconnection"<<endl;exit(1);}
   9  myconnection->connect();
  10  delete mydrivermanager;
  11 }

This is the shortest hk_classes program. First create a object instance of hk_drivermanager(). It handles the databasedriver management.

To connect to a SQL server you need a instance of hk_connection. By creating it, the wished database driver will be selected. When you connect with the "connect()"-command the password and some other information will be asked.

Nothing really visible happens here.To get in contact with your data just see the next chapters.
