| I would love to have a functionality doing this in the language.
Good! That's the important thing, really. The SQL bits were really
only in there so that people would understand what I meant. I can
rewrite it to make sure that it's understood to only be an example.
| I wonder whether this can be done more elegantly in the language
| than with that heavy-handed LIMIT/OFFSET. So if the SQL part is
| omitted or deemphasized...
Will do that.
| XQuery, btw, had already the concept of ordered list and uses
| XPath's position() function to limit the range. It is probably
| debatable whether this is elegant, but, hey, its XML anyway. :-)
If we could provide features that would let us do this indirectly that
would be the best.
| If the language already has lists, then a simple
|
| function I_want_results (..., $lower as natural := 0, $nr as natural :=
15) {
| ....
| return @results[$lower, $lower + $nr]
| ....
| }
|
| could do the job without hardcoding this into the language.
Conceivably, yes.
