Below you see the program of chapter 1 with some additional commands. A hk_database object represents a database, the name of the database can be set either with the constructor or with "set_name(const string&)".
A table or a query is be represented by a hk_datasource object (a query with a "SELECT statement is called in hk_classes a resultquery and can be created with hk_datasource* mydatasource=mydatabase->new_resultquery(); ).
Before you can see the data of a datasource you have to enable it (then the SQL-statement will be executed). The last command ("dump_data()") is just added so that you can see the data, please don't use it in your code.
Example 2.1. Get in contact with a table
#define HAVE_SSTREAM 1
#include <hk_classes.h>
#include <iostream>
int main()
{
hk_drivermanager* mydrivermanager = new hk_drivermanager();
if (mydrivermanager==NULL) {cout <<"error creating mydrivermanager"<<endl;exit(1);}
hk_connection* myconnection = mydrivermanager->new_connection();
if (myconnection==NULL) {cout <<"error creating myconnection"<<endl;exit(1);}
myconnection->connect();
hk_database* mydatabase=myconnection->new_database("exampledb");
if (mydatabase==NULL) {cout <<"error creating mydatabase"<<endl;exit(1);}
hk_datasource* mydatasource= mydatabase->new_table("authors");
if (mydatasource==NULL) {cout <<"error creating mydatasource"<<endl;exit(1);}
mydatasource->enable();
//the following internal debugging command should not be used. It is used here for
//demonstration purposes only!!!!
mydatasource->dump_data(); // DON'T USE THIS COMMAND IN YOUR PROGRAMMS!!!
delete mydrivermanager;
}
