Yes, you must have such a table, or you have to iterate over existing
table.

No. Same reason why you cannot write a select returning all values from 1
to 1000. You must have table to iterate over.
When stored procedures are able to return sets (they do, but halfway: C
ones can, but no other language supports that), you may have it a bit
easier...
