Greetings!
A charge consists of a set of coils arranged in one or more stacks. It
is possible for a stack to be empty. I need a query that lists all
possible stacks, along with the coils that are in each stack (if any).
Charge 1 can have 4 stacks. Only stacks 2 and 3 are in use. A plain
ordinary query can get me:
Stack Coil Position
2 A 1
2 B 2
3 C 1
3 D 2
I need:
Stack Coil Position
1
2 A 1
2 B 2
3 C 1
3 D 2
4
The query is allowed to include the maximum possible number of stacks,
which is 8.
How can I get a result like this?
Thanks very much!
