Subject: Class of a tupel within inheritance hierachy
Date: Mon, 16 May 1994 16:03:56 +0200
Message-ID: <"irafs2.ira.957:16.04.94.14.04.35"@ira.uka.de> (raw)


Hi everybody!


Is there a query to find out to which relation a tupel belongs in an
inheritance hierachy?



Example:

create father (...)
create son1 (...) inherits (father)
create son2 (...) inherits (father)

retrieve (tupel.all) from tupel in father* 
where ....



How can I determine whether 'tupel' belongs to father, son1 or son2 ?


Thanks for help!

Gerhard
