Hi,
i have the following SQL-Problem:
We are using 2 tables. The first, called plan, is holding planned working times for employees per
tour:
plan.id_tour
plan.id_employee
plan.begin_time
plan.end_time
The second table 'work' stores the actual worked times for employees per tour:
work.id_tour
work.id_employee
work.begin_time
work.end_time
Employees can be multiple times assigned to one tour. One record will be created for every
assignment. They can also work multiple times in one tour.
Now i wanna merge this infos into one report. I wanna join the first plan entry for one employee in
one tour with the first work entry for one employee in one tour and so on.
How can i obtain that? A simply USING(id_tour, id_employee) -JOIN will not doit.
Thanks for any hints,
Thomas
