Talk:Conjunctive query

From Wikipedia, the free encyclopedia

I would like to typeset the example query as a multiline latex equation, or, at least, indent the second and third line. Unfortunately I could not figure out how to do it. Any help? —Preceding unsigned comment added by Brezenbene (talk • contribs)

[edit] undistinguished variables

could it be that their index has to run from k+1 instead of 1??? otherwise there is an overlap with the distinguished ones which somehow doesn't appear to make sense. -- Kku (talk) 12:03, 5 December 2007 (UTC)
