Databases??

[Warus]

How can I create Databases??
There's a short manual on orbworks.com but I don't understand it. I never createt a Database, so can anyone tell me a URL to a Website wher's a tutorial or explain it to me in this forum?

If it's possible, write it in German

In German (thanks to dictionary.com ):

um eine Datenbank am Ablauf zu erstellen, verwenden Sie die dbcreate()funktion. Ist hier ein Beispiel, das creats eine Datenbank ' FirstDb ' nannten und schreiben ' hallo Welt!', zu ihm:

<pre id=code><font face=courier size=2 id=code>
main()
{
dbcreat("FirstDb");
dbwrite("hallo Welt!");
dbclose();
}
</font id=code></pre id=code>

Wenn Sie eine Datenbank auf Ihrem PC bilden m?ɬ?chten, dann ?ɬºberpr?ɬºfen Sie aus http://www.individeo.net.

--------
Now in English:

To create a database at runtime, use the dbcreate() function. Here's an example that creates a database called 'FirstDb' and writes 'Hello World!' to it:

<pre id=code><font face=courier size=2 id=code>
main()
{
dbcreat("FirstDb");
dbwrite("Hello World!");
dbclose();
}
</font id=code></pre id=code>

If you want to make a database on your PC, then check out http://www.individeo.net .

Hope this helps.

First of all, there is a mistake in the listing. It should say dbcreat<b>e</b>("FirstDB");
Second, there is no help in retrieving the just stored information. Use the above listing to save one string value and the following code to retrieve it.

In German (thanks to my mum)

Zun?ɬ§chst einmal befindet sich ein Fehler im Listing. Es sollte dbcreat<b>e</b>("FirstDB");
hei?É??en. Desweiteren gibt es keine Information, wie man die Daten wieder einliest. Nutze den oben aufgef?ɬºhrten Code um einen String zu speichern und das folgende Listing, um ihn wieder einzulesen.

<pre id=code><font face=courier size=2 id=code>
dbopen("FirstDB");
puts(dbread('s'));
dbclose();
</font id=code></pre id=code>

The following code is a further (slightly more advanced) db program. Here we are storing integers in a db. We are then reading these back.

I hope it helps. I am just getting to grips with databases myself.

//read db2
int i;
main(){
dbcreate("first db");
i=0;
clear();
while(i<6){
dbrec(i);
dbwrite(i*i);
i++;
}
i=0;
while(i<6){
dbrec(i);
puts(dbread("i")+"\n");
i++;
}
dbclose();
waitp();
}

i was hoping to find a way to list all the databases while having an interface similar to how PocketsC would list our compiled programs. The book doesn't seem to have that command available.

You can find all databases by using dbenum(). Displaying them is up to you - CControls is a good GUI library to start with.
