Belief me, you don't want to know ;)
I'm building a database application for the drugstore department.
Veterinarians can find medicines by searching on animal, ingredients,
diseases etc. When they've found one medicine all the detailed information
about this particular medicine is being displayed. At this point i thought
i could use the multiple selects.
The medicine has a 1 to many relationship with animals, ingredients,
diseases etc. all stored in different tables. When i use one single select
statement with several where conditions, and one relationship isn't filled,
the query returns nothing at all.

I'll split up one complex ZSQL method into several simple methods.
