Hello all,



I have a basic Oracle question:



What is 'dual'?  I've done a bit if reading from general purpose (IE,
non-Oracle specific) SQL books and they never mention the 'dual' table,
but I see it cropping up again and again in computations, so please,
enlighten me.  What is dual?  Mine currently has one field called
'dummy' and has a value of 'X'.



Sincerely,



Paul Cluiss
