Hallo Leute,
ich habe eine kleine Frage:
nachfolgend seht ihr mal mein SQL Statement, das super funkt,
aber nur ein Problem hat. N=E4mlich, wenn in einer Tabelle
mal nichts drinsteht, z.b. keine Links zu dem Thema vorhanden sind,
dann liefert das Statement gar nichts.=20
Ich w=FCrde es aber gerne so einrichten, das es mir alles liefert=20
was es findet.
Ist das m=F6glich?=20
Vielen Dank schon mal im vorraus!

Chris
