Hi Harald,

thanks for your kind answer.

yes, that is exactely what i am thinking, too. It isn´t possible, as far as
i´ve seen, to incorporate such arithmetic expressions within my query.
And as this is a feature, my resutling programm should support (a query like
the above one, or let´s say a query similar to: "show all realtions done by
User -X- since the last two weeks") i am in the process of finding a
solution...

hm... maybe a combination of SQL and Tolog (with SQL being used for the
arithmetic stuff, which tolog can´t handle and Tolog for the more general
queries).

Any input on how to do this, is, of course, appreciated :-). (but i think
it´s better to talk about this in a seperate topic :-) )

oh no, that´s not rude, you´re absolutely right. I am currently in the
process of finding my way into the Eclipse PlugIn Development and i will
hunt down the book, you´ve reccomended.

Thanks for this short introduction on how to this.

Thanks also for the offer of asking you. I guess i will come back to you in
a couple of days, if this is OK. ;-) Until then i´m going to get myself
knowledge onto the Eclipse Plugin development.


> No problem :) Hope i could help you a little bit...
Definitely, all of you guys on here are a great help for me.

Greetings
Andreas
