Hi Ruslan,
Could you give me a little hint on this issue too, please?

OK, lets assume, I have 3 tables.
t1:
1 John
2 Bob
t2:
1 personid1 taskid1
2 personid1 taskid2
3 personid1 taskid3
t3:
1 task1
2 task2
3 task3
How will the select statement look here, if I want to get all tasks in
t3, that are related to record 1 in t1?
Thanks,
Ralf
